Twitter is an online social networking and microblogging service that enables its users to send and read text-based posts of up to 140 characters, informally known as "tweets".

Twitter was created in March 2006 by Jack Dorsey and launched that July. Twitter rapidly gained worldwide popularity, with 200 million users as of 2011, generating over 200 million tweets and handling over 1.6 billion search queries per day. It is sometimes described as the "SMS of the Internet."

Twitter Inc., the company that operates the service and associated website, is based in San Francisco, with additional servers and offices in San Antonio, Boston, and New York City.
