Sketching out twitter
Dorsey sketches out Twitter
Inspired by early blogging pioneer LiveJournal, Dorsey conceives of a more live LiveJournal while living in Oakland, a service in which posts appeared in real-time and “from the road.” The idea was “akin to updating your AIM status from wherever you are, and sharing it,” he later wrote in a Flickr caption attached to an early sketch of what would become the Twitter interface. The idea stuck with Dorsey, weaving its way into his dispatch work. -
Dorsey was defeated and moved back to St.Louis
Dorsey is fired from the dispatch company, In his idle time, he comes up with the idea for a chair-massage service for programmers to help with their wrist aches, but ultimately drops the idea. He also gets a nose ring and an S-shaped tattoo. on him. -
Moving back to San Fransisco
Desperate to get back to programming, Dorsey agrees to look after Kidd’s children in exchange for housing and lives in a shed on the Berkeley–Oakland border.

On March 21st 2006......
At 12:50PM on March 21st, 2006, Dorsey sends out the first public tweet: “just setting up my twttr.” Around 12 minutes later, he adds, “inviting coworkers.” Twttr launches to the public on July 15th, 2006, and is renamed later that year to Twitter. Glass, who was dealing with the dissolution of his marriage, becomes unpredictable in public-speaking events and has routine outbursts at fellow employees over the direction of the product, leading Williams to fire him. Contention still exists over wh -
The creation of " Twittr"
After Apple’s introduction of podcasts in the new version of iTunes, Odeo’s business model was in tatters. Williams decides to hold a hackathon to come up with a new direction for the company. Dorsey, still enthralled by the idea of real-time networks and communication platforms, decides to marry SMS, the messaging network for cellphones, with a website that would bounce people’s status updates at one another. The idea eventually picks up steam, with help from Odeo co-founder Noah Glass, and Dor -
Also in 2006
In an alternative telling of who came up with the idea of Twitter, Glass recalls sitting in his parked car with Dorsey at 2AM. while the two sobered up after a night of drinking. Glass is listening to Dorsey’s real-time status updating pitch, something Glass had heard before, and Dorsey expresses disappointment that the Odeo higher-ups don’t seem to realize its potential. In an “epiphany,” Glass comes up with an different version of the idea in which -
Becoming CEO of Twitter
Twitter begins amassing users at an accelerated pace after it goes viral at the South by Southwest festival in March.

That summer, Twitter receives a $5 million Series A investment round. -
Jack founds square
Dorsey gets the idea for a mobile-payment company when his friend from St. Louis, Jim McKelvey, is unable to sell his glass faucets for $2,000 because he has no way to accept credit cards.

In 2008....
Following a second funding round and increasing public attention, Williams and prominent board member Fred Wilson come to the conclusion Dorsey is unfit to lead the company. The board cites Dorsey’s inability to solve a persistent outage issue that is causing the service to crash routinely, the lack of any type of backup for the entire Twitter system, and Dorsey’s tendency to leave work early to attend fashion design and yoga classes. Williams delivers to Dorsey the now-famous line, “You can eit -
Jack begins emulating Steve Jobs
Now into his second leadership stint at a up-and-coming tech startup, Dorsey begins dressing and speaking like the late Apple co-founder Steve Jobs. The emulation draws criticism of Dorsey, who begins altering versions of the Twitter origin story in public interviews and causes public relations problems for Williams and the Twitter board. Dorsey also sows discontent within the board by convincing new board member and investor Peter Fenton that Williams had sleighted Dorsey during the CEO handoff -
Dorsey re-jons Twitter after Williams leaves
Thanks in part to Dorsey’s efforts to undermine Twitter’s leadership, the company’s board replaces Williams with then-COO Dick Costolo in October 2010, citing Williams’ inability to manage the site’s growth, increase investor returns, and build out a more experienced executive team. Six months later, Dorsey rejoins Twitter as executive chairman with a focus on product development. Dorsey begins splitting his time between Twitter and Square. -

Becoming CEO of Twitter again !
After years of uncertain growth, a slumping share price, and an inability to refine Twitter’s long-term vision, Costolo resigns from his CEO role at Twitter in July. Dorsey steps back in as interim CEO. After a three-month-long search by a committee that included Williams, Dorsey is named the permanent CEO of Twitter in October. He will continue to split his time between Twitter and Square, which is now a multibillion-dollar company preparing for an IPO later this year
