Start with Netflix and Amazon Prime Video, tack on an HBO subscription to the latter, and consider paying for the Brit-centric streaming service Acorn as well. You’ll have plenty to watch, all commercial-free, and if you hear a lot of buzz about a show that isn’t available through any of those platforms, you can always pay for them on an episode-by-episode basis from Amazon (or iTunes, Vudu, or whichever digital retailer you prefer).
One of my personal favorites is Amazon Prime, which gives you access to thousands of free TV shows, movies, and documentaries, and there are thousands of other movies and shows available on a pay per view basis. There is a monthly fee to use Amazon Prime, but it is much more than just a TV subscription as you can also get free 2-day shipping from Amazon, borrow Kindle books for free, and more – all for less than $8 a month (Amazon Prime is one of the best deals in the tech world, in my opinion!).
If you want to join them but don't want to ditch live TV completely, you've come to the right place. Live TV streaming services in the US like Sling TV and DirecTV Now let you watch most if not all of your favorite live TV channels -- from ABC to CBS to CNN to ESPN to Fox News to Nickelodeon -- streamed over the internet. And the monthly fee is likely far less than you're paying the cable company for TV.
