Aereo%u2019s live TV coming to Chromecast in May - CNET. Over the air broadcast TV is available with an antenna everywhere. Aereo uses the Internet to rebroadcast open TV for a fee. Broadcasters have sued the company, and it defends itself by arguing that the signals of broadcast TV are free and over the air, and it can resell those signals if it wishes. The Supreme Court will hear the issue on April 29th, and, pending a decision one way or the other, Aereo has apps that will use Roku boxes, and Chromecast to rebroadcast the TV signals. Should make for an interesting summer. Watch on.
