CBS Corp. says it has made a minority investment in Syncbak, a technology company that allows mobile device users to pick up signals from their local TV stations over the Internet.
Founded in Marion, Iowa, in 2009, Syncbak allows people who download the app to watch local programming, even over a cellphone connection.
Broadcasters like CBS are hoping to reach consumers on new platforms as viewing habits change.
CBS said Monday that Syncbak's technology is being tested by more than 100 TV stations in 70 markets, including San Francisco, Philadelphia and Dallas.
CBS said it would work closely with cable, satellite and telecommunications companies on building Syncbak.
That suggests that getting the full use of Syncbak could require a pay-TV subscription, although that hasn't yet been decided.
