I recently switched from regular satellite TV to streaming, and it's easy. You need good internet and a Roku or Firestick hooked to your TV. Then, you choose apps like Netflix or Hulu to watch shows and movies. You can't record shows like old-school DVR, but you can watch stuff from their library anytime, which is handy.
I also started using IPTV, which is pretty cool. I pay 15 euros a month and get loads of excellent channels and tons of movies. Plus, I went for a yearly deal at 99 euros. The cool thing is I can watch it anywhere, even on my phone. It's a good deal, and I get to watch lots of stuff without paying a ton.
