Twitter Company Profile

Twitter

Twitter, founded by Jack Dorsey, Biz Stone, and Evan Williams in March 2006 (launched publicly in July 2006), is a social networking and micro-blogging service that allows users to post their latest updates. An update is limited by 140 characters and can be posted through three methods: web form, text message, or instant message. The company has been busy adding features to the product like Gmail import and search. They recently launched a new site section called “Explore” for external and third party tools that interact with Twitter and a new visualization tool called Twitter Blocks.

The service was started by Obvious Corp, who also started Odeo.

In April 2008 Twitter launched Twitter Japan in partnership with Digital Garage.
