I do not watch much TV to begin with, but when I do, I will load up Netflix and see if anything catches my eye. Most times I'll spend 30 minutes looking for something and then simply give up and move on to something more interesting. Having access to even more content just makes the problem worse, not better.
Sometimes I'll catch wind of good programming recommendations from others, but those sources are easily exhausted. The internet does a much better job. I can just turn up here and I'll probably find at least 50% of the links interesting at any given time. TV needs something like that.
