It's battle of the streams in the Supreme Court. On Tuesday, justices heard arguments over whether TV streaming company Aereo is circumventing copyright laws. Aereo downloads TV programs from public airways and stores them online to be accessable to customers via the Internet. TV networks say Aereo is stealing, while Aereo says it's leasing antennas to customers and is just acting as a mediator. If the court sides with broadcasters against Aereo, the ruling could make cloud services like like DropBox liable for infringement too.
