Internet TV company Aereo expands ahead of its Supreme Court date

Aereo is just days away from a decisive Supreme Court battle against the major broadcasters, but that's not stopping the company from aggressively expanding.

The company, which uses its antennas to capture free over-the-air broadcasts and then routes them to users over the Internet, raised $34 million in January bringing its total to $97 million in venture funding. Aereo is using that money to expand its business.

The company also announced on Thursday that Google's Chromecast will support Aereo starting in May.

Yet in just 11 days Aereo will go to trial to defend itself against allegations from major broadcasters that its service violates copyright law.

So why is the company forging ahead as if it has already won the case? Because the company believes that the law is in its favor, said CEO Chet Kanojia at Fast Company's Innovation Uncensored conference on Thursday.

"I believe in my facts, I believe in the legal process, I believe in my team I am 100 percent convinced that if you look at it as a matter of law and as a matter of policy we are dead right," Kanjoia said.

"I'm not in the business of predicting outcomes, but I like the groundwork that has been laid."

Aereo, which has already won several court cases brought against it, is contending that its service is just a new way of providing the same service that has been available for decades. The company's antennas basically let people stream free broadcast television via their connected devices. Users can also record shows on a virtual DVR.

The company's goal is to ultimately move TV to the cloud, Kanjoia said. But broadcasters are trying to stop Aereo because the company doesn't have to pay retransmission fees to the broadcasters with the use of its "personal antennas."

Cable companies, on the other hand, are required to pay broadcasters to access broadcasters' signals.

"It's very complicated and it's controlled in a very empire-ish sort of way. There is an immense amount of money-making happening," he said.

"It was a fantastic idea, but its time has come and gone in some ways," Kanojia added, referring to the way the broadcasting business model is set up.
