What is Twitter?
Twitter is a privately funded startup with offices in the SOMA
neighborhood of San Francisco, CA. Started as a side project in March of 2006, Twitter has grown into a real-time short messaging service that works over multiple networks and devices.
In countries all around the world, people follow the sources most relevant to them and access information via Twitter as it happens—from breaking world news to updates from friends. See what people are doing right now.
Jack Dorsey had grown interested in the simple idea of being able to know what his friends were doing. Specifically, Jack wondered if there might be an opportunity to build something compelling around this simple status concept. When he brought the idea up to his colleagues, it was decided that a prototype should be built.
Twitter was funded initially by Obvious, a creative environment in San Francisco, CA. The first prototype was built in two weeks in March 2006 and launched publicly in August of 2006. The service grew popular very quickly and it soon made sense for Twitter to move outside of Obvious. In May 2007, Twitter Incorporated was founded.
