The battle between broadcast networks and Aereo is about to become must see TV. Several networks complained that the Barry Diller-funded streaming service is threatening their bottom lines by retransmitting their signals without permission. The Supreme Court said today it will hear the broadcast networks’ case. For $8 a month, Aereo lets users stream and record over-the-air channels in some cities by using small antennas. The case, American Broadcasting Companies v. Aereo Inc., could push Aereo out of business.
