Twitter, online microblogging service for the dissemination of short messages via personal computer or mobile phone between groups of recipients.

Barack Obama defeated his rival, John McCain, in the social media arena in the 2008 U.S. presidential race, amassing almost four times as many Myspace friends and more than twenty times as many Twitter followers.
