What happened to the HD era?

They push HDTVs on us (in the U.S.) in every Sunday ad. In 1-2 months Hollywood will join the fray with HD-DVD and Blu-Ray discs... so why are there still so darn FEW HD channels?

The networks and PBS switched. But the only cable channels that my cable co. carries in HD are HBO/Max, Showtime, Discover, TNT, ESPN, and sports channels I couldn't give 2 squirts about.

How unexciting. For all the pushing they do, there's not a whole lot to look forward to yet. Discover and HBO I can get into. But where is Sci-Fi? Where is Spike? Comedy Central? I was starting to get excited about the Series3 Tivo coming later this year, but then I realized how thin the HD lineup still is. Very few additions in the last 2 years, which is an eon in technology progress.

The HD revolution is not being televised.
