Twitter Timeline (aka ‘X’): From Founding to Present
Few platforms have so profoundly shaped the 21st-century media and political landscape as Twitter. Launched in 2006 as a quirky microblogging experiment in Silicon Valley, Twitter rapidly evolved into a global public square — a real-time newswire, activism megaphone, cultural barometer, and political battleground all in one. From the Arab Spring to #BlackLivesMatter, celebrity feuds to presidential declarations, Twitter didn’t just reflect the world — it influenced it.
But in 2022, everything changed.
The takeover by Elon Musk, the billionaire tech entrepreneur and self-styled “free speech absolutist,” marked a sharp and chaotic break from Twitter’s legacy. In short order, Musk dismantled key moderation teams, reinstated accounts once banned for extremism or disinformation, and transformed the platform into a private entity under his X Corp umbrella. The iconic blue bird gave way to a stark new identity: X — signaling not just a rebrand, but a fundamental shift in mission, culture, and political alignment.
This timeline chronicles Twitter’s full arc from inception to its present incarnation as X: a detailed account of its business milestones, technological evolution, political influence, and growing alignment with right-wing ideology under Musk’s ownership. Drawing on a wide range of journalistic and academic sources, this narrative highlights how a once-fractious but largely liberal-leaning tech company became a controversial hub for “anti-woke” politics, misinformation, and culture war skirmishes — with global implications.
2006 – Birth of a New Platform
- March 2006: In a brainstorming at Odeo (a San Francisco podcast startup founded by Noah Glass, Biz Stone, and Evan Williams — the latter of whom would go on to later found the longform writing platform Medium), Jack Dorsey and colleagues conceive a text-message status sharing service. By March 21, Dorsey sends the first-ever tweet – “just setting up my twttr”, marking Twitter’s official creation.
- July 2006: Twitter (then styled “twttr” as was the vowel-less fashion at the time) launches to the public as a microblogging platform allowing 140-character posts. It initially operates under Odeo, but in October the founders form the Obvious Corporation and buy out Odeo’s investors, acquiring Twitter’s intellectual property.
- August – September 2006: Early users begin to see Twitter’s potential. In August, tweets about a California earthquake demonstrate Twitter’s value for real-time news by eyewitnesses. In September, twttr is rebranded as Twitter after acquiring the domain, finally graduating into the land of vowels.
2007 – Rapid Growth and Social Buzz
- March 2007: Twitter gains international buzz at the SXSW conference Interactive track. Usage explodes when attendees use it for real-time updates, a tipping point that greatly expands Twitter’s userbase.
- April 2007: Spun off as its own company, Twitter, Inc. begins to operate independently from Obvious Corp, the parent company of Odeo. Twitter also closes its first venture funding round in April, raising $5 million led by Union Square Ventures and venture capitalist Fred Wilson, who would become one of Twitter’s most influential backers, at a ~$20 million valuation. Other early investors included Ron Conway, Marc Andreessen, Chris Sacca, Joi Ito, and Dick Costolo (who would later become its CEO).
- August 2007: User-driven innovation gives rise to the hashtag. Invented by user Chris Messina to group topics, the “#” hashtag debuts and later becomes an official Twitter feature for trend tracking. This year, Twitter’s growth is so rapid that frequent server crashes occur, introducing the world to the iconic “Fail Whale” error image created by artist Yiying Lu (a symbol of its early growing pains).
