Like other Twitter applications it interfaces with the Twitter API to allow users to send and receive tweets and view profiles. It was the most popular Twitter application with a 23% market share as of June 2009, following only the official Twitter website with 45.7% share for posting new status updates.
TweetDeck's interface consists of a series of customisable columns, which can be set up to display your Twitter timeline, mentions, direct messages, lists, trends, favorites, search results, hashtags, or all tweets by or to a single user. The client supports URL shortening which can be done on-the-fly. All columns can be filtered to include or exclude words or tweets from users. Tweets can be sent immediately or scheduled for later delivery.
TweetDeck was originally developed by Iain Dodsworth, and launched on July 4, 2008. Dodsworth received his initial $300,000 seed funding a year later from The Accelerator Group, Howard Lindzon, Taavet Hinrikus, Gerry Campbell, Roger Ehrenberg, betaworks, Brian Pokorny, and Bill Tai. The company raised a Series A round of funding with many of these same investors, and Ron Conway, Danny Rimer, and the SV Angel group.
On May 25, 2011, TweetDeck was bought by Twitter for £25 million, after a bidding war with Bill Gross's UberMedia. On September 15, 2011, TweetDeck tweeted that new updates for all of its versions would be released and that "As part of the process of making TweetDeck more consistent with Twitter.com & Twitter's mobile apps, we're removing deck.ly from our apps." Many users expressed their anger at this feature removal in the comments on the iOS and Android Market. Deck.ly previously allowed users to post tweets in excess of 140 characters. The app has also long been left with only an unstable build when used under iOS 5.
Twitter released an entirely different software branded "TweetDeck by Twitter" on December 8, 2011, as part of Twitter's redesign of its services. TweetDeck changed from an Adobe AIR application to a native Windows and Mac OS X application in this release, and also introduced a web version of TweetDeck for WebKit-based browsers based on TweetDeck's existing Google Chrome app. The update dropped support for LinkedIn, Google Buzz, Foursquare, MySpace accounts.
On January 22, 2013, The American directors of Twitter were sent a letter by Companies House (the United Kingdom Registrar of Companies) warning them that their UK subsidiary TweetDeck Ltd. was at risk of closure, over missed accounting deadlines.
The letter stated: "The Registrar of Companies gives notice that, unless cause is shown to the contrary, at the expiration of 3 months from the above date the name of TweetDeck Ltd will be struck off the register and the company will be dissolved." 
On March 4, 2013 TweetDeck announced in a blog post that they would be suspending mobile versions of TweetDeck including TweetDeck AIR, TweetDeck for iPhone and TweetDeck for Android, which will be removed from their respective app stores this May. TweetDeck said they would "focus our development efforts on our modern, web-based versions".
On May 2, 2013, users were informed that 'Facebook is no longer supported in TweetDeck', and that on May 7, Facebook accounts and Facebook columns will be removed. No further explanation was provided.
On May 7, 2013, TweetDeck Ltd, was officially struck off the business register by Companies House, and dissolved, for failure to file accounts for 2011. This has no bearing on the product or service which is now run by Twitter, not by TweetDeck Ltd.
Originally, as it is now, TweetDeck was aimed towards the Twitter social networking service. Over the years, TweetDeck introduced support for other social networks, but has since removed that support.
On March 16, 2009, a pre-release version was released featuring Facebook status updates integration. As of April 8, 2009, Facebook status updates were part of the standard program. From version 0.30 TweetDeck also supported MySpace integration. Version 0.32, released on November 30, 2009, added LinkedIn integration and new Twitter features. In May 2010 TweetDeck also added integration with the Google Buzz and Foursquare social networks.
In 2012 TweetDeck reverted to only supporting Twitter and Facebook, ending support for LinkedIn, MySpace, and the now defunct Google Buzz effective June 2012.
In May 2013, Twitter removed support for Facebook accounts, becoming focused once again on the core Twitter experience.
An alternate version of TweetDeck, called TweetDark, provides the same functionality as the original application with a completely reskinned appearance. Another alternate version, TweakDeck, retains some features altered after the purchase of the original application by Twitter. It will cease functionality in early May 2013 because of more restrictive API version 1.1.
