Twitter started in 2006 when the podcasting company Odeo realized they needed to reinvent themselves and began brainstorming new creative ideas. Jack Dorsey introduced the idea of creating an SMS that would allow a user to communicate with a small group of people.

Twitter was first called "status" until the group looked in the dictionary for names and found twitter which fit it perfectly. The original product name was twttr.

The project work began on March 21, 2006, when Dorsey published the first Twitter message: "just setting up my twttr". The prototype for twitter was tested as an internal service for Odeo employees but later launched publicly in July 2006.

In October 2006, Jack Dorsey, Biz Stone and Evan Williams formed Obvious Corporation with other members from Odeo. They then bought out Odeo from the investors and other shareholders. In April of 2007, Twitter became its own company.
