Aereo lets users stream and record live over-the-air TV to their computers, phones and tablets by providing them with dime-size antennas and online cloud storage. "There is a generation of people today who are picking and choosing their own media experience, that does not want to be dictated to," said Virginia Lam, Aereo's vice president of communications and government relations. "If the government wants to give them permission to steal our signal, then we will come up with some other way to get them our content and so get paid for it," CBS chief executive Leslie Moonves said at an investors meeting last month. The Obama administration has sided with the broadcasters, saying in a brief that Aereo is "clearly infringing" on the networks' copyright by streaming content without permission. Aereo has built its technology on the legal loophole that every subscriber uses his or her own tiny antenna to watch and record a unique copy of a TV program. Before Tuesday's Supreme Court arguments, Aereo stepped up efforts to take its case to the public through various media appearances by its CEO, including an interview with Yahoo anchor Katie Couric.
