Microblogging site Twitter this morning unveiled its plan to make money through advertisements.
The advertising program, which Twitter calls "Promoted Tweets," will show up when Twitter users search for keywords that the advertisers have bought to link to their ads. Later, Twitter plans to show promoted posts in the stream of Twitter posts, based on how relevant they might be to a particular user, The New York Times reports.
Several companies will run ads, including Best Buy, Virgin America, Starbucks and Bravo.
Since Twitter started in 2007, its growth has resembled a hockey stick, increasing almost in a vertical line. According to comScore, Twitter.com had 22.3 million unique visitors in March, up from 524,000 a year ago.
