I get by with the following apps:
- PBS - Free and requires no subscription (you do have to register on the PBS website for HD, but that's free as well), most PBS shows are available but a few are not like Hometime.
- Crackle - Similar to PBS (free/register for HD) but has ads. A good number of free movies and TV shows as well as original content like "Comedians In Cars Getting Coffee". Definitely check it out if you haven't before.
- YouTube - I signed up for YouTube Red ($10/month) to get rid of ads. Most of my nightly viewing is YouTube videos. The app UI is not great but works.
- HBO Now - Available without a cable subscription ($15/month), I signed up last season for Game of Thrones then canceled, and will sign up again for this season of GoT then cancel again. Episodes available same-day as broadcast. If you haven't tried it they have a 30-day free trial.
- iTunes Home Sharing - For several years I only bought movies and TV shows on iTunes, I use a file server with iTunes running on it to download my purchases to and then stream them locally. Same thing for video podcast subscriptions in iTunes (namely Twit.tv shows).
Regarding
SHO, apparently they have an independent streaming service similar to
HBO NOW. As for
SyFy and
FX they are only available with a cable subscription as far I as know. When I first cut the cord I weened myself off of the cable teat by buying season passes for shows I liked on iTunes. The only problem with doing that is the shows tend to get released on iTunes later than they originally aired. For example, "Top Gear" (UK) would release to iTunes 4-5 months after airing, while "Little People, Big World" would release the day after airing. For 2-3 shows a year this costs far less than subscribing to cable, just got to be okay with missing out on cooler talks at work.
