Twitter site to carry advertising

Twitter, the social- networking service whose users post about 50 million short messages a day, will start running advertising to generate sales from marketers eager to reach its audience.

The blogging site, founded in 2006, will carry “promoted tweets” from advertisers including Best Buy and Starbucks, according to a blog post from the company yesterday. At the outset, the ads will appear at the top of search pages. – (Bloomberg)
