The Grand Alliance was really stuck with a 19.2 Mbps data rate from the 
beginning. They could have probably given the progressive standard a few 
more lines of resolution but they were having a difficult time getting 
progressive video to work acceptably and were running out of time.

Yes, I understand that but it was interlaced from the beginning. I'm 
grateful for that because 1080i looks utterly beautiful and I'd hate to 
be stuck watching only 720p every day. I doubt I would have bought an 
HDTV if 720p was the only format. For filmed material it's only somewhat 
better than a good DVD and the benefits of progressive scan video are 
rarely seen (mostly during long pans).

If you know how to cram 1080p 60 fps into 19.2 Mbps with MPEG-2, dozens 
of companies will want your help.

Which gets the HDTV consumer what exactly?

Calling thousands of people idiots is easy. Creating a standard for a 
complicated consumer product that has affected every part of a huge 
industry is a difficult task. But it works and I thank every one of 
those idiots for making it possible.
