Hi there, welcome to modern television!
Joking/trolling aside, I ditched the cable tv subscription a long time ago and I haven't looked back. To me, paying for shows on Netflix (subscription) or iTunes is worth it even if purely for the absence of advertisement!
In my current setup, I have an appleTV (3rd gen, I don't play games and it's been fine so far), I have an HBO Now subscription and a Netflix streaming+Blu-ray subscription as well (yes, I also have a Blu-ray player and a Mac mini HTPC with all my DVDs ripped while the discs themselves take on the dirt in the basement). I got the BD subscription mostly because I got tired of iTunes' US movie rental restrictions (the fact that you only have 24 hours to watch a movie is incompatible with my less than 2 year old kid who seldom gives us 2 full hours to sit down – French rentals allow 48 hours!). The other advantage of the disc rentals is that things come out fairly quickly, especially compared to Netflix streaming.
One thing though, I very rarely watch sports, usually just the soccer World Cup every four years but that streamed to the Apple TV so that worked out fine.
Cheers!
Alex.
