We buy shows from iTunes for the Apple TV. The shows have no commercials. Do Netflix shows have no commercials. Hulu shows commercials and doesn’t show the tv shows sometimes for a whole month after airing.
Netflix has no commercials. $8/month all-you-can-watch. Only caveat is their library, albeit huge, tends to not have the latest still-high-value content (there’s iTunes and RedBox for that), and some of the titles come and go (and come, and go) depending on licensing status. There’s more than enough to watch - commercial free.
Netflix is commercial-free. However, I believe the major advantage of iTunes or Hulu over Netflix would be that new episodes are available the day after they originally air, whereas on Netflix, you wait until they're available on DVD.
So, if you're trying to keep current on stuff that's showing right now, you're better off going the iTunes or Hulu route, but for catching up on older shows, Netflix is the better option.
For me, when my current commitment with DirectTV expires, I plan on cutting off cable/satellite altogether and going with some form of iTunes/Netflix/Hulu plus of course, my own DVD library. Looking at the current options, either the AppleTV or Roku would likely serve, but I'm still far enough away from actually doing anything that there's no point making detailed plans yet.
Netflix have no commercials, and cost $8 or whatever it is a month unlimited.
