Evan Williams is a computer programmer and internet entrepreneur who has founded several Internet companies. Williams was previously chairman and CEO of Twitter, one of the top ten websites on the Internet. He also founded Blogger and Medium, two of the largest and most notable blog distribution websites.
In 1996 Williams moved to Sebastopol, California in Sonoma County to work for the technology publishing company O'Reilly Media. He started at O'Reilly in a marketing position, later becoming an independent contractor writing computer code, which led to freelance opportunities with companies including Intel and Hewlett-Packard. While he was working at O'Reilly, he also started a website called EvHead.com, where he first began blogging about his personal thoughts.
Evan Williams and Meg Hourihan co-founded Pyra Labs to make project management software. A note-taking feature spun off as Blogger; Williams coined the term "blogger" and was instrumental in the popularization of the term "blog". Blogger was acquired by Google on February 13, 2003.
Williams officially left Google on October, 2004, to co-found Odeo, a podcast company. In late 2006, Williams co-founded Obvious Corporation with Biz Stone and other former Odeo employees, to acquire all previous properties from Odeo's former backers. In 2007, Odeo was acquired by Sonic Mountain. Among Obvious Corporation's projects was Twitter, spun out into a new company in April 2007, with Williams as co-founder, board member, and investor. In October 2008, Williams became CEO of Twitter, displacing Jack Dorsey, who became chairman of the board.
