Mark Cuban, at his Blog Maverick site, makes the case that HDTV is an Internet video killer, and that it will save network TV:

HDTV is the Internet video killer. Deal with it. Internet bandwidth to the home places a cap on the quality and simplicity of video delivery to the home, and to HDTVs in particular. Not only does internet capacity create an issue, but the complexity of moving HDTV streams around the home and tp the HDTV is pretty much a deal killer itself. Together, internet video is destined for the PC monitor for a long time to come. The only wild card that will have an impact is gaming consoles, but they dint offer access to internet video, they all kill themselves by only offering access to content inside their walled gardens. Internet video won’t replace TV. It wont even complement TV offerings. It will flourish in the office. It will be a fun way to share personal content privately or publicly. It will be Community Access TV.

On the flip side, HDTV is here and now. Its gone from being a future technology that could be cool in our living room to being the King of this holiday shopping season. 10s of millions of HDTVs have been sold and will be sold in the next year. The number of households with HDTVs is exploding. Yet for reasons I cant figure out, the broadcast networks are ignoring the opportunity it presents.

The 4 broadcast networks are really the only 4 companies that create content on a daily basis that can put smiles on the faces of all those HDTV buyers. They broadcast most of their prime time signals over the air and have the greatest reach on cable and satellite HD delivery.

While Cuban makes an interesting point, he ignores the fact that people’s attention is moving away from TV to Internet video and video podcasts despite the fact that Internet video usually looks crappy.

Problems with resolution and file size will be relatively easy to solve, compared to network tv’s dependency on intrusive advertising.
