Cable companies

After seeing the music industry revolutionized from CD to MP3 so quickly, I can't believe the question of movies haven't been tackled sooner.

1) Innovation. When are cable companies going to think outside the box? Video on Demand should put Blockbuster out of business (unless Blockbuster uses a server to harddrive idea of movie rentals). But VOD isn't any good yet. The movie selection is weak, and the navigation to find the movies is piss poor at best. Also, using portable storage devices is a GREAT idea, a revolutionary idea. But what will happen in a few years when bandwidth increases?

2) Integration. Right now many people have a computer in their house (we have 7) and several TVs. When is a company going to fully integrate the two? Furthermore when is a company (Charter would be ideal) going to allow users to purchase what they see on TV. This would do away with commercials as we know them. For instance, you can click on Kobe's shoes and be able to buy a pair just like them...furthermore Amazon.com type companies would pay a premium to be the store of choice. This would revolutionize TV/advertising/retail, yet noone is doing it.

What are your thoughts?
