100% of my television viewing is done on the internet for free, through either network sites, Hulu, or video sharing sites. I use Hulu sometimes for old TV shows, but most of the current stuff requires Hulu Plus, so for current stuff I usually use the networks. Hulu irritates me because they will let you watch the first season of an older show, and then tell you you need Hulu Plus to watch the rest of the seasons. But since I've started using the internet exclusively, there has only been one show that I really want to watch that I haven't been able to find for free somewhere, and that's "The Sopranos".
As for movies, most people I know who have paid subscription services prefer Netflix to Hulu Plus, because of the movies by mail option, and also because Hulu Plus makes you watch commercials. I hear the problem with Amazon Video is simply that the selection is much smaller than Netflix or Hulu. But if you order a lot from Amazon, it's free if you join Amazon Prime, which also gives you Kindle books and free two-day shipping.
