Twitter users, including actor Patrick Stewart (R), rings the opening bell at the New York Stock Exchange (NYSE) while also celebrating Twitter's IPO on November 7, 2013 in New York City.

Since it was founded in 2006, Twitter has evolved from a simple way for people to stay updated on their friends to an integral part of how information spreads, particularly for news organizations. Read on for the full history of the social media company, from Jack Dorsey's brainchild at a now-defunct podcasting company to its recent saga involving billionaire Elon Musk's Twitter takeover bid.

Blogger creator Ev Williams and NYU student Jack Dorsey had a momentous brainstorm

Twitter was born at a brainstorming event hosted by board members at the now-defunct podcasting company Odeo, which was founded by Noah Glass and Twitter's first CEO, Evan "Ev" Williams. Williams had previously founded the blog engine Blogger and is currently the founder and CEO of Medium.

One of the attendees at the brainstorm was then NYU undergrad student Jack Dorsey, who came up with the idea of using SMS technology (the earliest form of text messaging) to share updates with a group of friends. Remember, back in 2006, there was no such thing as a group text chain. Soon, the first-ever "tweet" was sent from Dorsey's account, @jack.

March 21, 2006: Jack Dorsey posted the first-ever message to Twitter

The first-ever tweet was hardly profound—just a short message from Dorsey reading, "just setting up my twttr." More than 15 years later, an NFT of Dorsey's first tweet sold for crypto amounting to $2.9 million.

July 15, 2008: Twitter became available to the public

Dorsey and a contractor named Florian Weber developed the earliest version of the app, which was launched to the public on July 15, 2006, after operating privately as a messaging service for Odeo employees.

October 2016: Twitter founders formed Obvious Corporation and acquired Odeo and its assets

Seeing the value of Twitter early on, Biz Stone, Williams, Dorsey, and other Odeo employees formed a new holding company, Obvious Corporation, and acquired Odeo and Twitter from Odeo's investors. The fifth Twitter founder, Noah Glass, was fired around this time, and his role in launching Twitter remained unknown until 2011. However, unlike similar jilted founders like Eduardo Saverin at Facebook and Reggie Brown at Snapchat, Glass never sued, though he was eventually granted a small amount of equity in Twitter.

March 2017: Twitter was the talk of South by Southwest

Twitter had its big break at 2007's SXSW in Austin. The company displayed huge screens constantly updating with live content from Twitter. Throughout the then five-day music festival and tech expo, attendees started using Twitter themselves to update on the events of the week. By the end of the week, Twitter usage had tripled.

April 2007: Twitter spun off from Obvious Corp. as its own company with Jack Dorsey as CEO

While Twitter is arguably Obvious's biggest success, the venture capital firm, still operated by Biz Stone, helped launch other noteworthy brands, such as vegan brands Beyond Meat and Miyoko's Creamery as well as the photo and video editing platform VSCO.

During Dorsey's first tenure as CEO, he completed two funding rounds. This period also led to launching support on the app for hashtags, which grew organically from a method users had adopted to organize tweets about a common subject.

October 2008: Jack stepped down and Evan Williams stepped up

Many Twitter users these days have probably never heard of, let alone seen, a "Fail Whale." But in the app's early years, outages during peak use were very common. Frustrated users would try to reload their feeds only to be greeted instead with the image of a smiling whale being lifted out of water by several orange birds. Outages are common with a rapidly growing platform, but the ubiquitous Fail Whale was just one of many signs that Dorsey hadn't matured yet into the type of leader Twitter needed at this stage in its development. According to rumors, he didn't even have a backup for Twitter's database. He was asked to step back into the role of chairman while Williams took over as CEO. He went on to launch promoted tweets, the first monetization of the platform.

December 2017: Twitter threads debuted

Of course, Twitter threads didn't invent the concept of users sending multiple tweets in a narrative thread, but Twitter made it a lot easier for people to get long-winded by integrating the ability to construct a long thread of tweets and send them all at once. Before that, threads would be created by users creating a string of multiple replies below an original tweet.

There was also an upswing in targeted harassment. Twitter made a number of changes to the platform and attempted to curb both these negative user experiences. Users were given the ability to limit who could reply to a specific tweet to either only people mentioned or those followed by the user. Content deemed misleading or false started to get screened with warnings to the reader.

April 14, 2022: Musk made a tender offer to purchase Twitter for $43 billion

Musk made it clear that he wanted to take over Twitter and address a number of problems he has with the platform, namely the lack of transparency in its algorithm and content and account moderation issues he believed were stifling free speech on the platform. Twitter initially tried to prevent the takeover bid with a poison pill defense but ultimately accepted Musk's offer.

July 8, 2022: Musk withdrew his offer and a legal battle started

Musk claims in a regulatory filing that Twitter was in material breach of contract for failure to comply with his requests for information on spam accounts—a claim Twitter refutes—and he would therefore not proceed with the deal. In response, Twitter has vowed to sue to force Musk to honor the terms of the deal. At minimum Musk could be held to a $1 billion breakup fee for not following through with the deal.
