So, you are ALSO abusing the term "broadcasting" since the 5% of revenues doesn't apply to audio/visual (or advertiser-supported) services sent in the clear.
And, if you would rather start from scratch, you are destined to fail, but then, you can't start, can you?
Wow, impressive, "up to 480", when the whole world is looking at "bigger things." I'd say that's not an attribute, but a limitation.
Wow impressive! Once again John demonstrates his lack of understanding of the issue of resolution versus screen size, and the positive benefits of oversampling relative to emission formats.
Apple's new iTune movie rental service uses 640 x 360 resolution. This is essentially the equal to SD-DVD, which is dumbed down by the need to limit vertical resolution for INTERLACED displays. 

Once again John:

480P is more than adequate for display up to about 40 inch diagonal;
720P is more than adequate for displays up to about 70 inch diagonal, and can deliver better quality in a bit-rate constrained channel than 1080P.
People MAY be buying bigger TVs for their family rooms, but there is much greater growth in the number of small displays that can be used to view video.

Craig
