The talk of the town this morning is Aereo, a Internet-TV service backed by Barry Diller’s IAC/InterActiveCorp and formally unveiled Tuesday, that offers to stream broadcast TV signals to mobile phones, tablets and fixed connected devices for $12 a month. The service initially will only be available in New York City, but the company plans to expand to other markets as it grows. Probably not before taking a detour through federal court, however. Other efforts to stream broadcast signals, such as Ivi.tv, have been shut down over copyright issues, and yesterday, Aereo officials acknowledged they expect to face legal challenges. Can Aereo succeed in court where Ivi.tv failed? Aereo claims to have modeled the design of its system on Cablevision’s remote DVR service, which the courts have declared to be legal. I’ll have more on that in an upcoming Weekly Update. For now, though, Aereo should make an interesting test case for how to build potentially ruinous litigation into an startup launch plan.
