CBS Corp chief executive Leslie Moonves and News Corp deputy chairman Chase Carey said that they are in no hurry to let Google TV offer their shows via the web for free as the search company has not made any lucrative offers to the broadcasters so far.
CBS recently blocked its detective show NCIS and News Corp's Fox blocked its primetime musical comedy series Glee from being aired on Google TV.
Prime time shows aired online have about four minutes of ads per hour, compared with 16 minutes on broadcast. Media analysts said that the television networks are likely to lose about 75 per cent of sales per viewer when the shows are aired online instead of on TV.
"We need to understand better what they're going to do," Carey said. Moonves said CBS is not currently in any formal negotiations with Google as it is not offering to pay the TV networks for its shows.
