Yahoo has acquired a Palo Alto, Calif., start-up called IntoNow, whose technology is designed to help television viewers discover programs and discuss them interactively with their friends.

IntoNow's application, launched in January and available for the iPhone, detects the sound of TV programs coming from TV sets or computers and attempts to identify the program and specific episode that's playing.

IntoNow has indexed more than five years of U.S. television programs in its database. If it identifies a match, it lets users share the name of the TV program they're watching and related information with their friends. This can be done via the IntoNow application or other social media services like Facebook and Twitter. Viewers can also exchange comments about the show.
