FTC Is Asking Questions About Twitter

The Federal Trade Commission is taking a closer look at Twitter, sending a query about possible antitrust behavior to another tech firm that has sparred with the social-networking site. UberMedia, which makes products allowing users to access Twitter from mobile phones, confirmed Thursday that it was contacted by the FTC about Twitter. The company declined to give specifics about the inquiry, but UberMedia has fought with Twitter in recent months about whether it can continue offering Twitter-related apps.
