With Youtube Premium, the no-ad benefit works on all devices. So if you pay the $14, you don't get ads on your computer, your phone, and any smart TVs you've got that have the YouTube app installed. For me that's a big deal because I got rid of cable TV years ago so almost everything I watch on TV is through Youtube or Netflix. We were using Hulu for TV for a while but recently cancelled it because they were charging me an additional $6.99 per month for no ads but they were showing ads all the time on various shows we were watching, which was annoying.
