JACK IS BACK: Twitter Inventor Jack Dorsey Is Working For Twitter Again

Jack Dorsey and Evan Williams

Twitter inventor Jack Dorsey is back working at the company on a once-a-week-or-so basis, three industry sources tell us.

Dorsey was Twitter CEO until the company’s chairman and top investor,  Ev Williams, pushed him out and took the top job for himself in Fall 2008.

Dorsey is working on “fixing” Twitter’s product, sources say.

Interesting. When Ev himself got pushed out of the CEO slot in October, Twitter PR told everyone it was because he wanted to focus more on product.

Some sources say Jack is back on new Twitter CEO Dick Costolo’s request, and that Ev isn’t thrilled about it.

Whatever the case, we think it’s brilliant of Twitter to bring back its inventor.

Jack Dorsey could not be reached for comment. Nor Twitter.

circa 2000 - 2001, Jack Dorsey comes up with an idea

These pages now hang framed in Twitter's offices. Cofounder Jack Dorsey told the L.A. Times he drew them up around 2000 or 2001.

'It was crystallizing the thought: What if you have LiveJournal, but you just make it more live? You have these people watching your journal, but it all happens in real time, and you can update it from anywhere. That document was an exploration of that concept.'

May 2006, Twttr launches

March 2006, Twitter's first tweet

We would have gone with something clever and allusive like '@Ev, Come Here. I need you.' But for Twitter's first message ever, Jack chose to simply answer the question Twitter still asks its users today: 'What are you doing?'

July 2006, TechCrunch covers Twttr

Reviewing Twitter for the first time in July 2006, TechCrunch founder Michael Arrington gave the service 'a thumbs up for innovation and good execution on a simple but viral idea.'

August 2006, Users tweet about a San Francisco earthquake

When a small earthquake shook San Francisco in August 2006 and word quickly spread through Twitter, it was an early 'ah-ha!' moment for users and company-watchers.

Today, dozens of companies make dozens of Twitter apps, for computers, set-top boxes, phones, etc.

March 2007, Twitter dominates SXSW

July 2007, Twitter raises $5 million.

Twitter launched as a product of another company, Odeo. But Odeo's founders saw its potential and bought out their own investors before launching Twitter as its own company.

That meant Twitter needing funding.

It got some from A-listers starting in July 2007 when Union Square Ventures, Charles River Ventures, Marc Andreessen, Dick Costolo, Ron Conway, and Naval Ravikant invested $5 million.

Correction: An earlier version of this post said Twitter raised $1 million. It raised $5 million.

April 2009, CNN acquires Twitter account CNNbrk

In April 2009, CNN found itself in a high-profile race to one million Twitter followers with C-list celebrity Ashton Kutcher.

CNN eventually lost, but it only had a chance because it opened its wallet and bought Twitter account @CNNbrk from a user who had hooked the account up to CNN's RSS feed months before.

The story demonstrates how quickly Twitter went from being a service mainstream media ignored to one it couldn't live without in Spring 2009.
