USA Today reports that Twitter might start making a profit from advertising. "Promoted Tweets" may appear on some Twitter.com search results, according to co-founder Biz Stone. The move already has followers: Best Buy, Bravo, Red Bull, Sony Pictures, Starbucks and Virgin America.

Responses to the business model were two-fold, the Guardian pointed out. Some felt that the site needed to make revenue "inevitably", while others doubt its success. ReadWriteWeb described it as "non-invasive," "nothing too crazy," "nothing terribly exploitive," "entirely predictable" and that it had "no banner ads" or "sales of data to direct marketers."

Later on this year, Twitter will be including ads in users feeds, ads that will be "relevant," the Los Angeles times reported. Promoted Tweets will offer relevant information whereas those that "don't resonate" with users will be removed, Stone said. Advertisers will be charged according to a cost-per-thousand system.

Promoted Tweets will be available as regular Tweets and will be sent to those who follow particular brands while one Promoted Tweet will show up on search results. They will also have all the features of regular Tweets, such as replying, Retweeting and favoriting.

"While we are excited about the platform in general, there are several specific aspects of the launch that we are delighted to highlight. Since all Promoted Tweets are organic Tweets, there is not a single 'ad' in our Promoted Tweets platform that isn't already an organic part of Twitter. This is distinct from both traditional search advertising and more recent social advertising," said the team behind the advertising model.
