It could also be to the detriment of the Internet by not supporting IPTV though! IPTV is more "net-neutral" than CATV because the cable franchises differentiate between & charge seperately for the video and data services they deliver over the same pipe. In our idealized, digital world, isn't it all the same?
What if in 3-5 years (or sooner), it's not necessary to pay twice?
I know that with the depth of engineering talent in the telecosm, on Google's engineering bench, with it's world class cloud-network, and technological innovation, amazing things are possible. Before you say, "the internet wasn't designed for multi-cast TV" Remember, it wasn't designed for Streaming, VoIP, or Music downloading either. A lot of people lost a lot of money because there once was a bandwidth "glut"
Google may someday soon seek to index & monetize CATV, but the Cable companies can meter for these new advanced services as much as telecoms can for theirs. The $ is the real fear from the "Telecom Hegemony" by the Net Neutrality lobby on behalf of the end user, isn't it? They are looking out for "our" best interests, aren't they?
