Latest revision as of 16:51, 1 October 2024

The history of Twitter, later known as X, can be traced back to a brainstorming session at Odeo.

Major events

[edit]
Time period Key developments at Twitter
March 2006 – March 2007 Twitter launches as a product of parent company Odeo. It grows slowly until March 2007, where usage grows dramatically after it is showcased at the South by Southwest Interactive (SXSW) conference.
April 2007 – October 2008 Twitter grows rapidly under CEO Jack Dorsey, completing two funding rounds and launching official support for hashtags.
October 2008 – October 2010 Jack Dorsey steps down, and Evan Williams takes over as CEO. Twitter raises money, gets celebrity endorsements and publicity, and continues to grow rapidly. The first tweet from space occurs during this period. Twitter also announces that it will start allowing for advertising in the form of promoted tweets – "ordinary tweets that businesses and individuals want to highlight to a wider group of users."
October 2010 – October 2013 Evan Williams steps down as CEO, and Dick Costolo takes over.
October 2013 Twitter announces plans and files relevant legal documents in October 2013 so as to go public. In November 2013, it has its initial public offering. Post-IPO, the company's pace of acquisitions increases dramatically.
November 2014 – present With the launch of features such as Instant Timeline, While You Were Away, Quality Filter, Curator, and Moments, Twitter diversifies beyond just being a reverse chronological stream of tweets by people you already follow.
July 2015 – present Dick Costolo departs Twitter and Jack Dorsey assumes the role of interim CEO. Commentators note that the "founder's instincts" are influencing the product's new direction.
April 2022 Elon Musk and Twitter board reach a deal for Musk to acquire the company for $44 billion and take it private.[1][2]
July 2023 Elon Musk rebrands Twitter to X.[3]

Full timeline

[edit]
Year Month and date Event type Event
2004 November Prelude Odeo, Twitter's parent company, is started.
2005 February Prelude Odeo's podcasting service is released, with very little public response.
2006 February 26–27 Creation Jack Dorsey, Noah Glass, Evan Williams and Biz Stone discuss the idea of using text messaging to share statuses, and decide to work on the project. The original idea is attributed to Jack Dorsey, and called the status concept.[4]
2006 Early March Creation The name Twitter (spelled twttr at the time and using a green site logo[5]) is chosen for the service. The idea for the name is attributed to Noah Glass.[6][7]
2006 March 21 Creation Twitter is officially set up and Jack Dorsey sends the first tweet.[8]
2006 July 15 Media coverage Noah Glass tells Om Malik about Twitter (then called twttr), and Malik writes what appears to be the first ever news coverage of Twitter,[9] and several people, including Malik himself, have commented on the accuracy (or lack thereof) of its predictions from the perspective of hindsight.[10][11][12]
2006 August 3 Usage Twitter users tweet about a mild (4.4 on the Richter scale) earthquake in California. The event helps Twitter's team see the potential of Twitter as a way for many people to contribute to the reporting of a live event, each from his or her own vantage point.[13]
