Following CBS's declaration that it will attempt to block Aereo from setting up shop in Boston, the Barry Diller-controlled company has asked a federal court in New York for a declaratory judgment that would in effect block the networks from filing lawsuits in cities where it wants to operate. The networks have so far been unable to demonstrate in court that Aereo's system -- in which a tiny antenna and DVR are assigned to each subscriber to allow them to watch broadcast shows on mobile devices on demand -- infringes on their copyrighted material. But the networks are not ready to throw in the towel. In an interview with CNBC on Monday, CBS chief Les Moonves said, Way too much has been spoken about Aereo and written about Aereo. ... It is not a serious threat to us. We think it's an illegal service -- we think they're taking our signal. Some analysts have estimated that Aereo has been able to attract a mere handful of subscribers. Others have suggested that the networks actually benefit from Aereo since it virtually eliminates cable channels from competition. Indeed, Moonves seemed to recognize that in the digital future, CBS would become a presence on a number of digital platforms. You'll get paid differently than you do today, he said during the CNBC interview. But you'll always get paid and you'll always win out. Content wins.
