Tonight, an NHL game between the New York Rangers and New York Islanders at Madison Square Garden will be broadcast live - in 3D - to customers who subscribe to the local MSG sports network and have television sets that can receive a 3D picture.
The audience is expected to be small, since few people have the sets. But the game is also being shown at the theater next to Madison Square Garden, at $20 a seat.
CBS News and CNET technology analyst Larry Magid says every new technology has to start somewhere - and this is one of those products that may have strong appeal for some people.
"Sports is one area where it's going to be interesting. I'm not convinced that it's going to take over sitcoms," Magid said. "But movies like Avatar, when they come out on 3D BlueRay, that's going to jumpstart some sales."
But for Magid, there are simply too many issues to make him want to run out and buy a 3D TV.
"There's a lot of confusion in the industry in terms of standards," he said.
In 1998, MSG was the first regular provider of sports coverage in high-definition television, producing all Knicks and Rangers home games in that emerging format., according to the company's press release.
The game will be shot using 3ality Digital's image-capturing technology, which integrates with existing broadcast equipment for pixel-perfect 3D imagery, MSG said.
