So whether it's 300 or 300 million the bandwidth for each channel is stilling being sent the way it is with satellite.
True, but the difference is the way the downstreaming happens. Currently there is no bandwidth issues when millions of people all watch TV from a coax signal. in addition, there are tens of thousands of sources for those coax TV signals, as each cable company is just a simple re-broadcaster of someone else's content. In addition to the millions of people that receive their signals over the air.
Internet streaming is an entirely different beast. There are fewer sources of the content, EVERYONE wishing to view Internet-only content has to watch it on the Internet. That bogs down ISP's, bringing down bandwidth. Add people watching Netflix, playing on-line games, being on Facebook, general computer traffic in general, and you have a recipe for complete net chaos..... ISPs would crash everywhere as a result. The only way for simultaneous Internet traffic to occur, with minimal effects on bandwidth, would be fiber optic.
Right now in a typical household, Dad could be watching football, mom watching something in the kitchen. Junior is listening to Pandora while he's playing COD on line. Sally is on Facebook, chatting on MSN and streaming a TV show in the background. Under the current 2011 model, only two of those people are online using bandwidth.
Under a potential Apple TV ALL of them would be on-line, putting their Internet ISP to the test. Now, multiply that world wide, every hour of every day, because the earth spins and there's always someone somewhere using the net, and you have a recipe for disaster. Only fiber optics allows simultaneous Internet traffic with virtually no effects to bandwidth.
Look at Netflix, that's one service only available to a small part of the world, and it's killing the Internet.
