I got rid of cable TV in 2009 when I was furloughed for 4 weeks, not sure if I'd have a job to go back to. Never got cable TV back but I kept cable internet all this time.
I watch a few shows via a combination of Netflix, Hulu, iTunes and ::cough::bittorrent::cough::...

For the first two, which can be delayed up to a year between broadcast and DVD release, I just try and avoid spoilers. Had to stop following Dexter on Facebook because of spoilers and the delay.
