Twitter marked its fifth birthday on Monday with a promotional video of celebrities talking up the world-changing micro-blogging service.
A video at discover.twitter.com featured billionaire entrepreneur Sir Richard Branson, tennis star Serena Williams, astronaut Paolo Nespoli, rapper Snoop Dogg and others explaining why they use Twitter.
Jack Dorsey fired off the first tweets on March 21, 2006, an automated "just setting up my twttr" message which he followed with the first "human" tweet, "inviting coworkers." It was Dorsey who proposed the idea for Twitter while working with Biz Stone and Evan Williams at podcasting company Odeo. Since then, Twitter has been embraced as a forum for sharing anything from a favorite lunch spot to violations of civil rights and calls for revolution.
Twitter users fire off messages at a rate of about a billion every eight days. In comparison, it took slightly more than three years and two months for the first billion tweets to be sent at the service. More than 140 million text messages of 140 characters or less are fired off daily at Twitter. The length limit was set to fit the maximum allowed in text messages sent using mobile phones.
