I don't have cable TV, and I don't have much interest in renting DVDs or Blue-Rays. I think they're all dying technology. Hulu is killing TV-as-TV, and streaming NetFlix is killing physical media for video. I do have a biggish TV in the living room, and it gets Netflix via the Wii. No Hulu out there, but I watch on my PC. All connected by wireless Ethernet.
There's one coax cable running into the house, and that's it. I can throw a funny hat over the modem and router and be done. So much nicer than running cables.
