In 1999, Mark Cuban tried to provide broadcast television programming over the Web through his Broadcast.com site.

The effort didn’t work—and neither has its present-day equivalent, Aereo, which last week learned that it won’t get the chance to be classified as a cable service. Aereo’s chances of reviving itself had already been slim, and now “look grimmer than ever” after the US Copyright Office decision, Brian Fung of the Washington Post blogged (see the full letter below).

On Saturday, Cuban wrote that Aereo “deserves a lot of credit for their effort,” which spawned a legal battle with broadcasters that reached the US Supreme Court. 

“It was a long and expensive shot to do what they went for. But they went for it. And they attempted to pivot after their SCOTUS loss,” Cuban wrote. “The technology has obviously gotten better on all sides of the equation, but sometimes a good idea is a good idea. Even if it is hard to make work.”

He added: “Everything old is always new again in tech.”
