Twitter Brings Back Jack Dorsey As Executive Chairman

Micro-blogging platform Twitter has announced the return of co-founder Jack Dorsey as the company's executive chairman, having responsibility for product development.

Dorsey, who was ousted as the CEO of the company in 2008, will replace fellow Twitter co-founder Evan Williams, who has decided not to remain involved in day-to-day work but willcontinue on the company's board.

Williams had replaced Dorsey as the CEO in 2008 but had to make way for Dick Costolo soon after that. Williams was responsible for product development within Twitter and was focused on coming up with a definite product road map for the future.

“As executive chairman, Jack will dive into work with more than 450 people, led by an experienced executive team,” Twitter said in a statement.

“The timing is fortuitous; not only is Twitter experiencing record growth, but we also now have a new infrastructure that will keep us ahead of that growth and enable us to launch products that will make Twitter more instant, simple and always present,” the company added.

Dorsey has said that he plans on remaining as CEO of his mobile payments platform Square as well. Square's offices are located very near to Twitter's headquarters in San Francisco.
