Twitter (initially called Twttr) is an American microblogging and social networking service on which users post and interact with messages known as "tweets". Registered users can post, like, and retweet tweets, but unregistered users can only read those that are publicly available. Users interact with Twitter through browser or mobile frontend software, or programmatically via its APIs. Prior to April 2020 services were accessible via SMS.[13] The service is provided by Twitter, Inc., a corporation based in San Francisco, California, and has more than 25 offices around the world.[14] Tweets were originally restricted to 140 characters, but the limit was doubled to 280 for non-CJK languages in November 2017.[15] Audio and video tweets remain limited to 140 seconds for most accounts.

2006–2007: Creation and total defense rebate - Crack Key For U reaction

Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Jack Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group.[25][26] The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass,[27] inspired by Flickr and the five-character length of American SMS short codes. The decision was also partly due to the fact that the domain was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service to Twitter.[28] The developers initially considered "10958" as a short code, but later changed it to "40404" for "ease of use and memorability". Work on the project started on March 21, 2006, when Dorsey published the first Twitter message at 9:50 p.m. PST (UTC−08:00): "just setting up my twttr".[3] Dorsey has explained the origin of the "Twitter" title:[30]

.we came across the word "twitter", and it was just perfect. The definition was "a short burst of inconsequential information", and "chirps from birds". And that's exactly what the product was.

The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service for Odeo employees.[31] The full version was introduced publicly on July 15, 2006.[11] In October 2006, Biz Stone, Evan Williams, Dorsey, and other members of Odeo formed Obvious Corporation and acquired Odeo, together total defense rebate - Crack Key For U its assets—including and—from the investors and shareholders.[32] Williams fired Glass, who was silent about his part in Twitter's startup until 2011.[33] Twitter spun off into its own company in Total defense rebate - Crack Key For U 2007.[34] Williams provided insight into the ambiguity that defined this early period in a 2013 interview:[35]

With Twitter, it wasn't clear what it was. They called it a social network, they called it microblogging, but it was hard to define, because it didn't replace anything. There was this path of discovery with something like that, where over time you figure out what it is. Twitter actually changed from what we thought it was in the beginning, which we described as status updates and a social utility. It is that, in part, but the insight we eventually came to was Twitter was really more of an information network than it is a social network.


The tipping point for Twitter's popularity was the 2007 South by Southwest Interactive (SXSWi) conference. During the event, Twitter usage increased from 20,000 tweets per day to 60,000.[36] "The Twitter people cleverly placed two 60-inch plasma screens in the conference hallways, exclusively streaming Twitter messages," remarked Newsweek's Steven Levy. "Hundreds of conference-goers kept tabs on each other via constant twitters. Panelists and speakers mentioned the phototheca pro review, and the bloggers in attendance touted it."[37] Reaction at the conference was highly positive. Photofiltre studio x crackeado download - Crack Key For U Scott Beale said that Twitter was "absolutely ruling" SXSWi. Social software researcher Danah Boyd said Twitter was "owning" the conference.[38] Twitter staff received the festival's Web Award prize with the remark "we'd like to thank you in 140 characters or less. And we just did!"[39]

In February 2010, Twitter users were sending 50 million tweets per day.[40] By March 2010, the company recorded over 70,000 registered applications.[41] As of June 2010, about 65 million tweets were posted each day, equaling about 750 tweets sent each second, according to Twitter.[42] As of March 2011, that was about 140 million tweets posted daily.[43] As noted on, Twitter moved up to the third-highest-ranking social networking site in January 2009 from its previous rank of twenty-second.[44]

Creamer on January 22, 2010.[51] By late November 2010, an average of a dozen updates per day were posted on the astronauts' communal account, @NASA_Astronauts.

Appearance and features

The Twitter account page for Wikipedia, demonstrating the account-customized timeline view which shows tweets in reverse chronological order

Tweets are publicly visible by default, but senders can restrict message delivery to only their followers. Users can mute users they do not wish to interact with, block accounts from viewing their tweets and remove accounts from their followers list.[160][161][162] Users can tweet via the Twitter website, compatible external applications (such as for smartphones), or by Short Message Service (SMS) available in certain countries.[163] Users may subscribe to other users' tweets—this is known as "following" and subscribers are known as "followers"[164] or "tweeps", a portmanteau of Twitter and peeps.[165] Individual tweets can be forwarded by other users to their own feed, a process known as a "retweet".

The counters for "likes", "retweets", and replies appear next to the respective buttons in timelines such as on profile pages and search results.

If you follow 20 people, you'll see a mix of tweets scrolling down the page: breakfast-cereal updates, interesting new links, music recommendations, even musings on the future of education.[173]

According to research published in April 2014, around 44% of user accounts have never tweeted.[174]

The first tweet was posted by Jack Dorsey (creator) at 12:50 PM PST on March 21, 2006, and read "just setting up my twttr".[175] In 2009, the first tweet was sent from space.

Content of tweets according to Pear Analytics

  News (3.6%)

  Spam (3.8%)

  Self-promotion (5.9%)

  Conversational (37.6%)

  Pass-along value (8.7%)

Pass-along value had 9%, self-promotion 6% with spam and news each making 4%.

Despite Jack Dorsey's own open contention that a message on Twitter is "a short burst of inconsequential information", social networking researcher danah boyd responded to the Pear Analytics survey by arguing that what the Pear researchers labeled "pointless babble" is better characterized as "social grooming" or "peripheral awareness" (which she justifies as persons "want[ing] to know what the people around them are thinking and doing and feeling, even when co-presence isn't viable").[179] Similarly, a survey of Twitter users found that a more specific social role of passing along messages that include a hyperlink is an expectation of reciprocal linking by followers.[180]


Hashtags, usernames, retweets and replies

"Twitter hashtag" redirects here. For more about hashtags, see Hashtag.

Since May 2020, users can select who can reply each of their tweets before sending them: anyone, accounts who follow the poster, specific accounts, and none. This ability was upgraded in July 2021 to make the feature retroactively applicable to tweets after they have been sent out.[185][186]

In late 2009, the "Twitter Lists" feature was added, making it possible for users to follow ad hoc lists of authors instead of individual authors.[164][187]

Using SMS

Through SMS, users can communicate with Twitter through five gateway numbers: short codes for the United States, Canada, India, New Zealand, and an Isle of Man-based number for international use. There is also a short code in the United Kingdom which is only accessible to those on the Vodafone, O2[188] and Orange[189] networks. In India, since Twitter only supports tweets from Bharti Airtel,[190] an alternative platform called smsTweet[191] was set up by a user to work on all networks.[192] A similar platform called GladlyCast exists for mobile phone users in Singapore and Malaysia.[193]

The tweets were set to a largely constrictive 140-character limit for compatibility with SMS messaging, introducing the shorthand notation and slang commonly used in SMS messages. The 140-character limit also increased the usage of URL shortening services such as,,,, and other content-hosting services such as TwitPic, and NotePub to accommodate multimedia content and text longer than 140 characters. Since June 2011, Twitter has used its own domain for automatic shortening of all URLs posted on its site, making other link shorteners unnecessary for staying within Twitter's 140 character limit.[195]

In August 2019, Jack Dorsey's account was hacked by using Twitter's SMS to tweet feature to send crude messages. Days later, the ability to send a tweet via SMS was temporarily turned off.[196]

In April 2020, Twitter discontinued the ability to receive SMS messages containing the text of new tweets in most countries.[197][198]

Character limits

In 2016, Twitter announced that media such as photos, videos, and the person's handle, would not count against the already constrictive 140 character limit. A user photo post used to count for a large chunk of a Tweet, about 24 characters.[199] Attachments and links would also no longer be part of the character limit.

On March 29, 2016, Twitter introduced the ability to add a caption of up to 480 characters to each image attached to a tweet.[201][202] This caption can be accessed by screen reading software or by hovering the mouse above a picture inside TweetDeck.

Since March 30, 2017, the Twitter handles are outside the tweet itself, therefore they no longer count towards the character limit.[203] Only new Twitter handles added to the conversation count towards the limit.

In 2017, Twitter doubled their historical 140-character-limitation to 280.[204] Under the new limit, glyphs are counted as a variable number of characters, depending upon the script they are from: most European letters and punctuation forms count as one character, while each CJK glyph counts as two so that only 140 such glyphs can be used in a tweet.[204]

URL shortener is a URL shortening service created by Twitter. It is only available for links posted to Twitter and not available for general use. All links posted to Twitter use a wrapper. Twitter hopes that the service will be able to protect users from malicious sites, and will use it to track clicks on links within tweets.[206]

Having used the services of third parties TinyURL and,[207] Twitter began experimenting with its own URL shortening service for private messages in March 2010 using the domain, before it purchased the domain. The service was tested on the main site using the accounts @TwitterAPI, @rsarver and @raffi. On September 2, 2010, an email from Twitter to users said they would be expanding the roll-out of the service to users. On June 7, 2011, Twitter announced that it was rolling out the feature.[195]

Trending topics

Main article: Twitter trends

Countries and cities with local trending topicsin Twitter

A word, phrase, or topic that is mentioned at a greater rate than others is said to be a "trending topic". Trending topics become popular either through a concerted effort by users or because of an event that prompts people to talk about a specific topic.[208] These topics help Twitter and their users to understand what is happening in the world and what people's opinions are about it.[209]

Trending topics are sometimes the result of concerted efforts and manipulations by preteen and teenaged fans of certain celebrities or cultural phenomena, particularly musicians like Lady Gaga (known as Little Monsters), Justin Bieber (Beliebers), Rihanna (Rih Navy) and One Direction (Directioners), and novel series Twilight (Twihards) and Harry Potter (Potterheads). Twitter has altered the trend algorithm in the past to prevent manipulation of this type with limited success.[210]

The Twitter web interface displays a list of trending topics on a sidebar on the home page, along with sponsored content (see image).

Twitter often censors trending hashtags that are claimed to be abusive or offensive. Twitter censored the #Thatsafrican[211] and #thingsdarkiessay hashtags after users complained that they found the hashtags offensive.[212] There are allegations that Twitter removed #NaMOinHyd from the trending list and added an Indian National Congress-sponsored hashtag.[213] President Donald Trump prosteted trends calling them "unfair, disgusting, illegal, ridiculous" claiming the ones that are bad about him are blown up.[214][215][216]


In October 2015, Twitter introduced "Moments"—a feature that allows users to curate tweets from other users into a larger collection. Twitter initially intended the feature to be used by its in-house editorial team and other partners; they populated a dedicated tab in Twitter's apps, chronicling news headlines, sporting events, and other content.[217][218] In September 2016, creation of moments became available to all Twitter users.[219]

Adding and following content

There are numerous tools for adding content, monitoring content and conversations including Twitter's own TweetDeck,, HootSuite, and As of 2009[update], fewer than half of tweets posted were posted using the web user interface with most users using third-party applications (based on an analysis of 500 million tweets by Sysomos).[220]

Verified accounts

Main article: Twitter verification

The official Twitter profile of Twitter, Inc. The blue check mark right of the profile name indicates that it is a verified account.

In June 2009, after being criticized by Kanye West and sued by Tony La Russa over unauthorized accounts run by impersonators, the company launched their "Verified Accounts" program.[221][222] Twitter stated that an account with a "blue tick" verification badge indicates "we've been in contact with the person or entity the account is representing and verified that it is approved".[223] In July 2016, Twitter adobe acrobat pro crack - Crack Key For U a public application process to grant verified status to an account "if it is determined to be of public interest" and that verification "does not imply an endorsement".[224][225][226] Verified status allows access to some features unavailable to other users, such as only seeing mentions from other verified accounts.[227]

In November 2020, Twitter announced a youtube download for pc of its verification system in 2021. According to the new policy, Twitter verifies six different types of accounts; for three of them (companies, brands, and influential individuals like activists), the existence of a Wikipedia page will be one criterion for showing that the account has "Off Twitter Notability".[228] Twitter states that it will re-open public verification applications at some point in "early 2021".[229]


Twitter has mobile apps for iPhone, iPad, Android, Windows 10, Windows Phone, BlackBerry, and Nokia S40.[231] Users can also tweet by sending SMS.[232] In April 2017, Twitter introduced Twitter Lite, a progressive web app designed for regions with unreliable and slow Internet connections, with a size of less than one megabyte, designed for devices with limited storage capacity.[233][234]

This has been released in countries with slow internet connection such as the Philippines.[235]

Twitter Lite has evolved into the main Twitter web interface, see section "interface".[citation needed]

Third-party applications

For many years, Twitter has limited the use of third-party applications accessing the service by implementing a 100,000 user limit per application.[236] Since August 2010, third-party Twitter applications have been required to use OAuth, an authentication method that does not require users to enter their password into the authenticating application. This was done to increase security and improve the user experience.[237]

Related headlines feature

This feature adds websites to the bottom of a tweet's permalink page. If a website embedded a tweet onto one of their stories, the tweet will show the websites that mentioned the tweet. This feature was added onto Twitter so if the viewer doesn't understand what the tweet means, they can click on the sites to read more about what the person is talking about.[238]


In 2015, Twitter began to roll out the ability to attach poll questions to tweets. Polls are open for up to 7 days, and voters are not personally identified.[239]

Initially, polls could have only two options with a maximum of twenty characters per option. Later[when?], the ability to add four options with up to 25 characters per option, was added.

Integrated photo-sharing service

On June 1, 2011, Twitter announced its own integrated photo-sharing service that enables users to upload a photo and attach it to a Tweet right from[240] Users now also have the total defense rebate - Crack Key For U to add pictures to Twitter's search by adding hashtags to the tweet.[241] Twitter also plans to provide photo galleries designed to gather and syndicate all photos that a user has uploaded on Twitter and third-party services such as TwitPic.[241]

Streaming video

In 2016, Twitter began to place a larger focus on live streaming video programming, hosting various events including streams of the Republican and Democratic conventions during the U.S. presidential campaign as part of a partnership with CBS News,[242]Dreamhack and ESLeSports events, and winning a bid for non-exclusive streaming rights to ten NFLThursday Night Football games in the 2016 season.

During an event in New York in May 2017, Twitter announced that it planned to construct a 24-hour streaming video channel hosted within the service, featuring content from various partners. CEO Jack Dorsey stated that the digital video strategy was part of a goal for Twitter to be "the first place that anyone hears of anything going on that matters to them"; as of the first quarter of 2017, Twitter had over 200 content partners, who streamed over 800 hours of video over 450 events.[246]

Twitter announced a number of new and expanded partnerships for its streaming video services at the event, including Bloomberg, BuzzFeed, Cheddar (Opening Bell and Closing Bell shows; the latter was introduced in October 2016) IMG Fashion (coverage of fashion events), Live Nation Entertainment (streaming concert events), Major League Baseball (weekly online game stream, plus a weekly program with live look-ins and coverage of trending stories), MTV and BET (red carpet coverage for their MTV Video Music Awards, MTV Movie & TV Awards, and BET Awards), NFL Network (the Monday-Thursday news program NFL Blitz Live, and Sunday Fantasy Gameday),[247] the PGA Tour (PGA Tour Live coverage of early tournament rounds preceding television coverage),The Players' Tribune, Ben Silverman and Howard T. Owens' Propagate (daily entertainment show #WhatsHappening), The Verge (weekly technology show Circuit Breaker: The Verge's Gadget Show), Stadium (a new digital sports network being formed by Silver Chalice and Sinclair Broadcast Group)[250][251][252] and the WNBA (weekly game).[246]

Account archival

Twitter has offered two different methods[clarify] of archiving one's own Twitter account data. Those methods have their individual benefits and disadvantages. As of September 2019, only the latter archival method is available.[citation needed]

In December 2012, Twitter introduced a "Tweet archival" feature, which created a ZIP file that contains an offline-browsable archive of all tweets.[253] Those exported tweets could be browsed and searched offline by using the bundled user-interface accessible through an Internet browser, which used client-side, JavaScript-powered pagination.[254] The user interface of the tweet archive browser had a design similar to Twitter's 2010–2014 desktop user interface, even until the feature's removal. The tweet text contents, ID's, time data and source labels are located in the file called "". It was possible to request at least one archive per day[verification needed]. The ability to export this type of tweet archive, which never existed on the new layout, has been removed entirely in August 2019[when exactly?], after co-existing with the new 2018 data archival method. Even when accessing the legacy Twitter desktop website layout using the user-agent of an older browser version, the option has disappeared from the account settings.


A social audio feature that enables users to host or participate in a live-audio virtual environment called space for conversation. Spaces can accommodate a maximum of 13 people (1 host, 2 co-hosts and 10 speakers) onstage and an unlimited number of listeners. The feature was initially limited to users with at least 600 followers. Since October 21, 2021, any Twitter user can create a Space from the Android or iOS app.[255]


In March 2020, Twitter began to test a stories feature known as "fleets" in some markets,[256][257] which officially launched on November 17, 2020.[258][259] Similarly to equivalent features, fleets can contain text and media, are only accessible for 24 hours after they are posted, and are accessed within the Twitter app via an area above the timeline.[256]

In June 2021, Twitter announced it would start implementing advertising into fleets, integrating full-screen ads among user-created content.[260] On July 14, 2021, Twitter stated that it would remove Fleets by August 3. Twitter had intended for fleets to encourage more users to tweet regularly, rather than simply consume other folks' tweets, but instead fleets were generally used by users who already tweeted a lot. The company stated that their spot at the top of the screen would now be occupied by currently active Spaces from the user's feed.[261]

On June 3, 2021, Twitter announced a service known as Twitter Blue, which provides features exclusive to those who are subscribers to the Twitter Blue service. They include:

  • Undo Tweet, which allows users to withdraw a tweet within a short time frame before it is posted.[262]
  • Bookmarks, which allows users to save individual tweets into folders.[262]
  • Reader mode, which converts threads of tweets into an article-like view.[262]
  • Color themes for the Twitter mobile app.[262]
  • Dedicated customer support.[262]

The service was initially released in Australia and Canada.[262] On November 9, 2021, Twitter Blue was launched for US customers.[263]

Tip Jar

In May 2021, Twitter began testing a Tip Jar feature on its iOS and Android clients. The feature allows users to send monetary tips to certain accounts, providing a financial incentive for content creators on the platform. The Tip Jar is optional and users can choose whether or not to enable tips for their account. The day the feature was launched, a user discovered that sending a tip through PayPal would reveal the sender's address to the recipient.[264]

On September 23, 2021, Twitter announced that it will allow users to tip users on the social network with bitcoin. The feature will be available for iOS users. Previously, users could tip with fiat currency using services such as Square'sCash app and PayPal'sVenmo. Twitter will integrate the Strike bitcoin lightning wallet service. It was noted that at this current time, Twitter will not take a cut of any money sent through the tips feature.[265]

The Shop Module

In July 2021, Twitter launched a test of The Shop Module, a shopping extension that directs customers to a brand's products from its official Twitter account. The feature initially launched for US-based users only and only on iOS.[266]

Safety Mode

On September 1, 2021, Twitter began to roll out Safety Mode, allowing users to reduce disruptive interactions. The rollout began with a small beta-feedback group on iOS, Android, and Twitter's web application.[267]

The functionality allows users to temporarily block accounts for seven days when potentially harmful language is detected. If a user has Safety Mode enabled, authors of tweets that are identified by Twitter's technology as being harmful or exercising uninvited behavior will be temporarily unable to follow the account, send direct messages, or see tweets from the user with the enabled functionality during the temporary block period. Jarrod Doherty, senior product manager at Twitter, stated that the technology in place within Safety mode assesses pc cleaner pro 2019 - Free Activators relationships to prevent blocking accounts that the user frequently interacts with.

Twitter first revealed Safety Mode in February 2021 within the Analyst Day slide deck.[268]

NFT Digital Assets

On September 23, 2021, Twitter revealed that it is experimenting with a feature that would allow users to authenticate and showcase their collections of NFT digital assets on the platform. The company did not provide specifics about the project but stated that it would be a way to support creators who make digital art.


Daily user estimates vary as the company does not publish statistics on active accounts. A February 2009 blog entry ranked Twitter as the third most used social network based on their count of 6 million unique monthly visitors and 55 million monthly visits.[44] In 2009, Twitter had a monthly user retention rate of forty percent.[269] Twitter had annual growth of 1,382 percent, increasing from 475,000 unique visitors in February 2008 to 7 million in February 2009. Twitter's annual growth rate decreased from 7.8 percent in 2015 to 3.4 percent in 2017.[270] An April 2017 a blog entry ranked Twitter as the tenth most used social network based on their count of 319 million monthly visitors.[271] Its global user base in 2017 was 328 million.[272] As per August 2018, Twitter light (data saving app) is available in 45 countries.[273]

In 2009, Twitter was mainly used by older adults who might not have used other social sites before Twitter, said Jeremiah Owyang, an industry analyst studying social media. "Adults are just catching up to what teens have been doing for years", he said. According to comScore only 11% of Twitter's users are aged 12 to 17. comScore attributed this to Twitter's "early total defense rebate - Crack Key For U period" when the social network first gained popularity in business settings and news outlets attracting primarily older users. However, comScore also stated in 2009 that Twitter had begun to "filter more into the mainstream", and "along UVK Ultra Virus Killer it came a culture of celebrity as Shaq, Britney Spears and Ashton Kutcher joined the ranks of the Twitterati".[277]

According to a study by Sysomos in June 2009, women make up a slightly larger Twitter demographic than men—53% over 47%. It also stated that 5% of users accounted for 75% of all activity and that New York City has more Twitter users than other cities.[278]

According to Quancast, 27 million people in the US used Twitter as of September 3, 2009; 63% of Twitter users are under 35 years old; 60% of Twitter users are Caucasian, but a higher than average (compared to other Internet properties) are African American/black (16%) and Hispanic (11%); 58% of Twitter users have a total household income of at least US$60,000.[279] The prevalence of African American Twitter usage and in many popular hashtags has been the subject of research studies.[280][281]

On September 7, 2011, Twitter announced that it had 100 million active users logging in at least once a month and 50 million active users every day.[282]

In 2012, the country with the most active users on Twitter was the United States.[283] A 2016 Pew research poll found that Twitter is used by 24% of all online US adults. It was equally popular with men and women (24% and 25% of online Americans respectively), but more popular with younger (36% of 18–29 year olds) generations.[284]

In an article published on January 6, 2012, Twitter was confirmed to be the biggest social media network in Japan, with Facebook following closely in second. ComScore confirmed this, stating that Japan was the only country in the world where Twitter leads Facebook.[285]

On March 31, 2014, Twitter announced that there were 255 million monthly active users (MAUs) and 198 million mobile MAUs. In 2013, there were over 100 million users actively using Twitter daily and about 500 million Tweets every day,[287] with about 29% of users checking Twitter multiple times a day.[288] As of Q1 2019[update], Twitter had more than 330 million monthly active users. The majority of Twitter users skew to the American political left.[289][290]

A 2019 survey conducted by the Pew Foundation found that Twitter users are more likely than the general public to have both a college degree and higher income than the average U.S. adult. Users are also three times as likely to be younger than 50 years old, with the median age of adult U.S. users being 40 years old. The survey found that 10% of users who are most active on Twitter are responsible for 80% of all tweets, focusing mainly on the topics of politics and women.[291]

Levels of use

About 22% of Americans say they have ever used Twitter, according to a 2019 Pew Research Center survey.[292] Noting how demographics of Twitter users differ from the average Americans, commentators have cautioned against media narratives that treat Twitter as representative of the population,[293] adding that only 10% of users Tweet actively, and that 90% of Twitter users have Tweeted no more than twice. In 2016, shareholders sued Twitter, alleging it "artificially inflated its stock price by misleading them about user engagement." The company announced on September 20, 2021 that it would pay $809.5 million to settle this class-action lawsuit.[294]


The Twitter logo from September 14, 2010, to June 5, 2012, featuring the silhouette version of "Larry the Bird"

Twitter has become internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the word "Twitter", was in use from its launch in March 2006. It was accompanied by an image of a bird which was later discovered to be a piece of clip art created by the British graphic designer Simon Oxley.[295] A new logo had to be redesigned by founder Biz Stone with help from designer Philip Pascuzzo, which resulted in a more cartoon-like bird in 2009. This version had been named "Larry the Bird", specifically after Larry Bird of the NBA's Boston Celtics fame.[296][297]

Within a year, the Larry the Bird logo underwent a redesign by Stone and Pascuzzo to eliminate the cartoon features, leaving a solid silhouette of Larry the Bird that was used from 2010 through 2012.[296] In 2012, Douglas Bowman created a further simplified version of Larry the Bird, keeping the solid silhouette but making it more similar to a mountain bluebird.[298] This new logo was called simply the "Twitter Bird" and has been used as the company's branding since.[296][299]


For the fiscal year 2017, Twitter reported losses of US$108 million, with an annual revenue of $2.443 billion, a decrease of 3.9% over the previous fiscal cycle. Twitter's shares traded at over $17 per share, and its market capitalization was valued at over US$25.6 billion in October 2018.

Twitter raised over US$57 million from venture capitalist growth funding, although exact figures are not publicly disclosed. Twitter's first A round of funding was for an undisclosed amount that is rumored to have been between US$1 million and US$5 million.[307] Its second B round of funding in 2008 was for US$22 million[308] and its third C round of funding in 2009 was for US$35 million from Institutional Venture Partners and Benchmark Capital along with an undisclosed amount from other investors including Union Square Ventures, Spark Capital, and Insight Venture Partners.[307] Twitter is backed by Union Square Ventures, Digital Garage, Spark Capital, and Bezos Expeditions.[309]

In May 2008, The Industry Standard remarked that Twitter's long-term viability is limited by a lack of revenue.[310] Twitter board member Todd Chaffee forecast that the company could profit from e-commerce, noting that users may want to buy items directly from Twitter since it already provides product recommendations and promotions.[311]

By March 2009, communications consultant Bill Douglass predicted in an interview that Twitter would be worth $1 billion within six months,[312] which came to pass when the company closed a financing round valuing it at $1 billion in September of that year.[313]

The company raised US$200 million in new venture capital in December 2010, at a valuation of approximately US$3.7 billion.[314] In March 2011, 35,000 Twitter shares sold for US$34.50 each on Sharespost, an implied valuation of US$7.8 billion.[315] In August 2010 Twitter announced a "significant" investment led by Digital Sky Technologies that, at US$800 million, was reported to be the largest venture round in history.[316]

In December 2011, the Saudi prince Alwaleed bin Talal invested US$300 million in Twitter. The company was valued at US$8.4 billion at the time.[317] In 2016, Twitter was valued by Forbes at US$15.7 billion.[318]

Revenue sources

In July 2009, some of Twitter's revenue and user growth documents were published on TechCrunch after being illegally obtained by Hacker Croll. The documents projected 2009 revenues of US$400,000 in the third quarter and US$4 million in the fourth quarter along with 25 million users by the end of the year. The projections for the end of 2013 were US$1.54 billion in revenue, US$111 million in net earnings, and one billion users.[319] No information about how Twitter planned to achieve those numbers was published. In response, Twitter co-founder Biz Stone published a blog post suggesting the possibility of legal action against the hacker.[320]

On April 13, 2010, Twitter announced plans to offer paid advertising for companies that would be able to purchase "promoted tweets" to appear in selective search results on the Twitter website, similar to Google Adwords' advertising model. As of April 13, Total defense rebate - Crack Key For U announced it had already signed up a number of companies wishing to advertise, including Sony Pictures, Red Bull, Best Buy, and Starbucks.[321][322]

The company generated US$45 million in annual revenue in 2010, after beginning sales midway through that year; the company operated at a loss through most of 2010.[314]

Users' photos can generate royalty-free revenue for Twitter, and an agreement with World Entertainment News Network (WENN) was announced in May 2011.[323] In June 2011, Twitter announced that it would offer small businesses a self-service advertising system.[324] Twitter generated US$139.5 million in advertising sales during 2011.

The self-service advertising platform was launched in March 2012 to American Express card members and merchants in the U.S. on an invite-only basis. Twitter later reported that numerous small businesses and people who used the self-service tool provided feedback that indicated they were impressed by the feature.[325] To continue their advertising campaign, Twitter announced on March 20, 2012, that promoted tweets would be introduced to mobile devices.[326] In April 2013, Twitter announced that its Twitter Ads self-service platform, consisting of promoted tweets and promoted accounts, was available to all U.S. users without an invite.[325]

Twitter's financial revenue statistics for the first quarter of 2014 was reported as US$250 million.

On August 3, 2016, Twitter launched Instant Unlock Card, a new feature that encourages people to tweet about a brand in order to earn rewards and utilize the social media network's conversational ads. The format itself consists of images or videos with call-to-action buttons and a customizable hashtag.[327]

Stock launch and tax issues

Twitter's San Francisco headquarters, as seen from a corner on Market Street

On September 12, 2013, Twitter announced that it had filed papers with the U.S. Securities and Exchange Commission (SEC) ahead of a planned stock market listing.[328] It revealed its prospectus in an 800-page filing.[329] Twitter planned to raise US$1 billion as the basis for its stock market debut.[330] The initial public offering (IPO) filing states that "200,000,000+ total defense rebate - Crack Key For U active users" access Twitter and "500,000,000+ tweets per day" are posted.[35][331] In an October 15, 2013, amendment to their SEC S-1 filing,[332] Twitter declared that they would list on the New York Stock Exchange (NYSE), quashing speculation that their stock would trade on the NASDAQ exchange. This decision was widely viewed to be a reaction to the botched initial public offering of Facebook.[333] On November 6, 2013, 70 million shares[334] were priced at US$26 and issued by lead underwriter Goldman Sachs.[335]

On November 7, 2013, the first day of trading on the NYSE, Twitter shares opened at $26.00 and closed at US$44.90, giving the company a valuation of around US$31 billion.[336] Consequently, executives and early investors marginally increased their capital, including co-founders Williams and Dorsey who received a sum of US$2.56 billion and US$1.05 billion respectively, while Costolo's payment was US$345 million.[337] On February 5, 2014, Twitter published its first results as a public company, showing a net loss of $511 million in the fourth quarter of 2013.[338] On January 5, 2016, CEO Jack Dorsey commented on a report that Twitter planned to expand its character limit to 10,000 (private messages already had the longer limit as of July), requiring users to click to see anything beyond 140 characters. He said while Twitter would "never lose that feeling" of speed, users could do more with the text.[339]

In September 2016, Twitter shares rose 20% after a report that it had received takeover approaches.[340] Potential buyers were Alphabet (the parent company of Google),[340]Microsoft,[341][342][343],[340][344]Verizon,[344] and The Walt Disney Company.[345][346] Twitter's board of directors were open to a deal, which could have come by the end of 2016.[340][347] However, no deal was made, with reports in October stating that all the potential buyers dropped out partly due to concerns over abuse and harassment on the service.[348][349][350] In June 2017, Twitter revamped its dashboard to improve the new user experience.[351][352]

In November 2017, the Paradise Papers, a set of confidential electronic documents relating to offshore investment, revealed that Twitter is among the corporations that avoided paying taxes by using offshore companies.[353] Later The New York Times reported that Russian-American billionaire Yuri Milner had strong Kremlin backing for his investments in Facebook and Twitter.[354]


In the 2018 US election cycle, 96.15% ($295,722) of donations of $200 or more from Twitter employees toward the category of "all federal candidates" went to Democrats, versus 3.85% ($11,850) to Republicans.[355]

Advertising bans

In October 2017, Twitter banned the Russian media outlets RT and Sputnik from advertising on their website following the conclusions of the U.S. national intelligence report the previous January that both Sputnik and RT had been used as vehicles for Russia's interference in the 2016 US presidential election.[356]Maria Zakharova for the Russian foreign ministry said the ban was a "gross violation" by the US of free speech.[357]

In October 2019, Twitter announced it would stop running political ads on its ad platform effective November 22. This resulted from several spurious claims made by political ads. Company CEO Dorsey clarified that internet advertising had great power and was extremely effective for commercial advertisers, the power brings morphvox full version free download risks to politics where crucial decisions impact Apk - Crack All Windows/Mac OS Software Full Version of lives.[358]

User Monetization

In February 2021, Twitter began testing different methods of monetizing users. This is in response to social platforms like Instagram, TikTok, Medium, Facebook, and Clubhouse increasingly focusing on monetizing platform creators. In June 2021, the company opened applications for its premium subscription options called Super Follows. This lets eligible accounts charge $2.99, $4.99 or $9.99 per month to subscribe to the account.[359] The launch only generated about $6,000 in its first two weeks.[360]

On August 27, 2021, Twitter rolled out Ticketed Spaces, which let Twitter Spaces hosts charge between $1 and $999 for access to their rooms.[361]



Twitter places great reliance on open-source software.[362] The Twitter Web interface uses the Ruby on Rails framework,[363] deployed on a performance enhanced Ruby Enterprise Edition implementation of Ruby.[364]

In the early days of Twitter, tweets were stored in MySQL databases that were temporally sharded (large databases were split based on time of posting). After the huge volume of tweets coming in caused problems reading from and writing to these databases, the company decided that the system needed re-engineering.[365]

From Spring 2007 to 2008, the messages were handled by a Ruby persistent queue server called Starling.[366] Since 2009, implementation has been gradually replaced with software written in Scala.[367] The switch from Ruby to Scala and the JVM has given Twitter a performance boost from 200–300 requests per second per host to around 10,000–20,000 requests per second per host. This boost was greater than the 10x improvement that Twitter's engineers envisioned when starting the switch. The continued development of Twitter has also involved a switch from monolithic development of a single app to an architecture where different services are built independently and joined through remote procedure calls.[365]

As of April 6, 2011, Twitter engineers confirmed that they had switched away from their Ruby on Rails search stack to a Java server they call Blender.

Individual tweets are registered under unique IDs called snowflakes, and geolocation data is added using 'Rockdove'. The URL shortener then checks for a spam link and shortens the URL. Next, the tweets are stored in a MySQL database using Gizzard, and the user receives an acknowledgement that the tweets were sent. Tweets are then sent to search engines via the Firehose API. The process is managed by FlockDB and takes an average of 350 ms.[362]

On August 16, 2013, Raffi Krikorian, Twitter's vice president of platform engineering, shared in a blog post that the company's infrastructure handled almost 143,000 tweets per second during that week, setting a new record. Krikorian explained that Twitter achieved this record by blending its homegrown and open source technologies.[365][368]

The service's application programming interface (API) allows other web services and applications to integrate with Twitter.[369]


Twitter introduced the first major redesign of its user interface in September 2010, adopting a dual-pane layout with a navigation bar along the top of the screen, and an increased focus on the inline embedding of multimedia content. Critics considered the redesign an attempt to emulate features and experiences found in mobile apps and third-party Twitter clients.[370][371][372][373]

The new layout was revised in 2011 with a focus on continuity with the web and mobile versions, introducing "Connect" (interactions with other users such as replies) and "Discover" (further information regarding trending topics and news headlines) tabs, an updated profile design, and moving all content to the right pane (leaving the left pane dedicated to functions and the trending topics list).[374] In March 2012, Twitter became available in Arabic, Farsi, Hebrew and Urdu, the first right-to-left language versions of the site. About 13,000 volunteers helped with translating the menu options.[375] In August 2012, beta support for Basque, Czech and Greek was added, making the site available in 33 different languages.[376]

In September 2012, a new layout for profiles was introduced, with larger "covers" that could be customized with a custom header image, and a display of the user's recent photos posted.[377] The "Discover" tab was discontinued in April 2015,[378] and was succeeded on the mobile app by an "Explore" tab—which features trending topics and moments.[379]

In September 2018, Twitter began to migrate selected web users to its progressive web app (based on its Twitter Lite experience for mobile web), reducing the interface to two columns. Migrations to this iteration of Twitter increased in April 2019, with some users receiving it with a modified layout.[380][381]

In July 2019, Twitter officially released this redesign, with no further option to opt-out while logged in. It is designed to further-unify Twitter's user experience between the web and mobile application versions, adopting a three-column layout with a sidebar containing links to common areas (including "Explore" that has been merged with the search page) which previously appeared in a horizontal top bar, profile elements such as picture and header images and biography texts merged into the same column as the timeline, and features from the mobile version (such as multi-account support, and an opt-out for the "top tweets" mode on the timeline).[382][383]


During an outage, Twitter users were Microsoft Office 2021 Crack free ActvationKey - Activators Patch one time shown the "fail whale" error message image created by Yiying Lu,[384] illustrating eight orange birds using a net to hoist a whale from the ocean captioned "Too many tweets! Please wait a moment and try again."[385] Web designer and Twitter user Jen Simmons was the first to coin the term "fail whale" in a September 2007 tweet.[386][387] In a November 2013 WIRED interview Chris Fry, VP of Engineering at that time, noted that the company had taken the "fail whale" out of production as the platform was now more stable.[388]

Twitter had approximately ninety-eight percent uptime in 2007 (or about six full days of downtime).[389] The downtime was particularly noticeable during events popular with the technology industry such as the 2008 Macworld Conference & Expokeynote address.[390][391]

User accounts

Privacy, security and harassment

Twitter messages are public, but users can also send private "direct messages".[392] Information about who has chosen to follow an account and who a user has chosen to follow is also public, though accounts can be changed to "protected" which limits this information (and all tweets) to approved followers.[393] Twitter collects personally identifiable information about its users and shares it with third parties as specified in its privacy policy. The service also reserves the right to sell this information as an asset if the company changes hands.[394] While Twitter displays no advertising, advertisers can target users based on their history of tweets and may quote tweets in ads[395] directed specifically to the user.

A security vulnerability was reported on April 7, 2007, by Nitesh Dhanjani and Rujith. Since Twitter used the phone number of the sender of an SMS message as authentication, malicious users could update someone else's status page by using SMS spoofing.[396] The vulnerability could be used if the spoofer knew the phone number registered to their victim's account. Within a few weeks of this discovery, Twitter introduced an optional personal identification number (PIN) that its users could use to authenticate their SMS-originating messages.[397]

On January 5, 2009, 33 high-profile Twitter accounts were compromised after a Twitter administrator's password was guessed by a dictionary attack.[398] Some of the compromised accounts sent falsified tweets, including drug-related messages.[399]

Twitter launched the beta version of their "Verified Accounts" service on June 11, 2009, allowing people with public profiles to announce their account name. The home pages of these accounts display a badge indicating their status.[400]

In May 2010, a bug was discovered by İnci Sözlük that could allow a Twitter user to force others to follow them without the other users' consent or knowledge. For example, comedian Conan O'Brien's account, which had been set to follow only one person, was changed to receive nearly 200 malicious subscriptions.[401]

In response to Twitter's security breaches, the United States Federal Trade Commission (FTC) brought charges against the service; the charges were settled on June 24, 2010. This was the first time the FTC had taken action against a social network for security lapses. The settlement requires Twitter to take a number of steps to secure users' private information, including maintenance of a "comprehensive information security program" to be independently audited biannually.[402]

On December 14, 2010, the United States Department of Justice issued a subpoena directing Twitter to provide information for accounts registered to or associated with WikiLeaks.[403] Twitter decided to notify its users and said in a statement, ". it's our policy to notify users about law enforcement and governmental requests for their information, unless we are prevented by law from doing so."[392]

A "MouseOver" exploit occurred on September 21, 2010, when an XSS Worm became active on Twitter. When a user held the mouse cursor over blacked-out parts of a tweet, the worm within the script would automatically open links and re-post itself on the reader's account.[404] The exploit was then re-used to post pop-up ads and links to pornographic sites. The origin total defense rebate - Crack Key For U the worm is unclear, but Pearce H. Delphin (known on Twitter as @zzap) and a Scandinavian developer, Magnus Holm, both claim to have modified a related exploit found by another user (possibly Masato Kinugawa) who was using it to create colored Tweets.[405] Kinugawa, a Japanese developer, reported the XSS vulnerability to Twitter on August 14. Later, when he found it was exploitable again, he created the account 'RainbowTwtr' and used it to post colored messages.[405] Delphin says he exposed the security flaw by tweeting a JavaScript function for "onMouseOver",[405] and Holm later created and posted the XSS Worm that automatically re-tweeted itself.[404] Security firm Sophos reported that the virus was spread by people doing it for "fun and games", but noted it could be exploited by cybercriminals.[404] Twitter issued a statement on their status blog at 13:50 UTC that "The exploit is fully patched."[404][406] Twitter representative Carolyn Penner said no charges would be pressed.[407]

In May 2011, a claimant known as "CTB" in the case of CTB v Twitter Inc. took action against Twitter at the High Court of Justice of England and Wales,[408] requesting that the company release details of account holders. This followed gossip posted on Twitter about professional footballer Ryan Giggs's private life. This led to the 2011 British privacy injunctions controversy and the "super-injunction".[409] Tony Wang, the head of Twitter in Europe, said that people who do "bad things" on the site would need to defend themselves under the laws of their own jurisdiction in the event of controversy and that the site would hand over information about users to the authorities when it was legally required to do so.[410] He also suggested that Twitter would accede to a UK court order to divulge names of users responsible for "illegal activity" on the site.[411]

Twitter acquired Dasient, a startup that offers malware protection for businesses, in January 2012. Twitter announced plans to use Dasient to help remove hateful advertisers on the website.[412] Twitter also offered a feature which would allow tweets to be removed selectively by country, before deleted tweets used to be removed in all countries.[413][414] The first use of the policy was to block the account of German neo-Nazi group Besseres Hannover on October 18, 2012.[415] The policy was used again the following day to remove anti-Semitic French tweets with the hashtag #unbonjuif ("a good Jew").[416] In February 2012, a third-partypublic-key encryptionapp

    If you haven't icare data recovery pro 8.0.5 licence code - Crack Key For U your 2020 tax refund, you are in good company.

    At the end of the 2021 filing season in May, the IRS had a backlog of 35 million tax returns that still needed to be manually processed, according to a report released Wednesday by the National Taxpayer Advocate, a government watchdog.

    The backlog includes about 16.8 million paper tax returns, some 15.8 million returns suspended for further review and 2.7 million amended returns. The backlog is nearly three times larger than it was in 2020, and a fourfold increase from 2019.

    The coronavirus pandemic and a shutdown to curb the spread of the disease is mostly to blame for the pileup, according to the report. Still, long wait times for refunds may be particularly harmful this year, especially for low-income Americans eligible for certain credits or those still waiting on stimulus checks.

    "For taxpayers who can afford to wait, the best advice is to be patient and give the IRS time to work through its processing backlog," wrote Erin Collins, the National Taxpayer Advocate, in her report to Congress.  "But particularly for low-income taxpayers and small businesses operating on the margin, refund delays can impose significant financial hardships."

    An overwhelmed IRS

    The 2021 tax filing season started late and was extended an extra month due to the coronavirus pandemic.

    To make matters worse, the agency was inundated with phone calls and unable to keep up. During the 2021 filing period, the IRS received 167 million phone calls, four times more than during the 2019 season. As a result, only 9% of calls were answered by a live customer service representative.

    The popular "1040" line, the most frequently dialed IRS toll-free number, received 85 million calls during the 2021 filing season, with only 3% of callers reaching a live person.

    Overall, the IRS processed most tax returns in a timely fashion in 2021, according to the report. In the last decade, funding to the agency has fallen by about 20%, leaving it less equipped to deal with the coronavirus pandemic.

    We cannot allow the agency to face the staffing and technology limitations it has experienced this past year.
    National Taxpayer Advocate

    In addition, the report only includes data through the end of the 2021 filing season, which ended May 17, meaning the IRS may have worked through more of the logjam since then.

    In a June hearing with the Senate finance committee, IRS commissioner Chuck Rettig said that as of May 28, the IRS had processed more than 137 million individual income tax returns and issued more than 101.2 million refunds totaling $281.4 billion. About 70% of taxpayers got money back in 2021, with an average refund of about $2,800.

    The IRS has also issued about 475 million economic impact payments totaling $807 billion in three separate rounds over the last 15 months. The agency also was tasked with managing monthly advanced child tax credit payments starting July 15.

    More funding driverpack solution offline full crack - Crack Key For U the horizon

    Going forward, the agency may gain more responsibilities from Congress, including further child benefits, energy credits and more.

    President Biden is also pushing for additional IRS funding to deal with the growing tax gap, and specifically to crack down on the wealthy that skirt taxes. The latest bipartisan infrastructure deal included more money for the IRS for this purpose.

    While the challenges faced by the IRS over the last year are understandable due to the pandemic, long wait times for refunds can be devastating for Americans, according to Collins.

    "Taxpayers cannot experience similar challenges in future filing seasons," Collins wrote in the report. "We cannot allow the agency to face the staffing and technology limitations it has experienced this past year."

    The World’s Fastest DES Cracker

    Behind is a system with 48 Xilinx Virtex-6 LX240T FPGAs. Each FPGA contains a design with 40 fully pipelined DES cores running at 400MHz for a total of 16,000,000,000 keys/sec per FPGA, or 768,000,000,000 keys/sec for the whole system. This means that it can exhaustively search the entire 56-bit DES keyspace in:

    256 / 768,000,000,000 = ~26 hours
    For comparison, the EFF DES Cracker had 29 boards x 64 chips each = 1,856 chips total, each chip did around 48,000,000 keys/sec for a total system speed of 90,000,000,000 keys/sec:

    256 / 90,000,000,000 = ~9.2 days
    To crack a key in the same amount of time as our system (26 hours) with other modern processors, you would need around:

    80,000 CPU cores
    ~$125,000 per key
    (at $0.12 per CPU on EC2)
    1,800 GPUs
    ~$20,000 per key
    (at $2.10 per GPU on EC2)


    We recently released support for running jobs with the plaintext of 1122334455667788 for FREE! We’re able to do this because we built one of the largest publicly available Rainbow Tables (Time-Memory Tradeoff Attack) for the entire DES keyspace (256). We are able to achieve an average crack time of 25 seconds and a success rate of 99.5%. If our system doesn’t crack your key immediately, it forwards the job on to our brute-force rig which will find the key within a couple days.
