Social networking website Twitter celebrates its fifth birthday today.

The micro-blogging site, which enables users to follow the antics of friends and celebrities via posted updates known as tweets,  was founded in March 2006 by Jack Dorsey, and has since grown from the simple idea of an individual using an SMS service to communicate with a small group to being one of the most popular forms of communication in the world and is today estimated to have over 200 million users, generating 65 million tweets a day.
