Given that Sky already sounds pretty confident about the possibility of a 2012 Olympics in 3D, we aren't shocked at all to find that its 3D tests have been successful thus far. Nevertheless, the BBC is reporting today that the satcaster has "successfully tested the delivery of 3D programming to a domestic television, via a high-definition set-top box." It has already begun to film a number of events in 3D over the past few months, and now that it has proven to itself that the technology is viable, it's working to find a way to bring it to viewers. In related news, the report also mentioned that Sky's director of strategic product development Gerry O'Sullivan stated that it now had "nearly 600,000 HD customers," and he even insinuated that HD was, in fact, not just "a niche product." That's the spirit, chap!
