Yeah, it still comes down to making the content available, and with Voom gone it looks like we'll have to hope for cable to lead the way for the time being.
As far as old programs and movies, they look great (at least old movies) when shown in HD, so that shouldn't be a problem. It's just getting HD transfers made of the material. I guess shows filmed on videotape aren't going to look great in HD, but old movies definitely do.
What's great about cable helping HD become accepted is that they don't usually require you to buy equipment like Dish and Directv do, so people are more likely to try it when they buy a new TV.
I think it's still the snowball effect, and it's just now starting to pick up steam and get bigger. Voom's demise is definitely a setback, but I still expect to see more content by the end of 2006. If Directv actually tries to do something besides HD-LIL with their new satellites, and if Dish could pick up the Voom originals in some for or other when they get Rainbow 1 maybe the outlook will change. With cable, of course, it just depends if you live in a good area and have a decent provider. Some of them are really decent.
TV prices continue to fall. When I bought my first HDTV, a 65" Toshiba, it was $3,500. I've seen 65" CRT HDTVs for around $1,800 recently. I remember seeing a 65" HDTV for $6,500 a couple years before I bought mine. It was a CRT also.
We're also starting to see smaller, affordable tube HDTVs now, even at places like Wal-mart. So at least things are progressing somewhat.
