Of course. I'm 30 and if it wasn't for live sport I'd never watch TV and even that is going away: Sky Germany lost the right to the british premier league and before that the spanish La Liga. Both, as well as the italian and french football leagues, are legally available at DAZN for 10 bucks a month. It's a great deal.
However besides sports the program just isn't there. It can't be since its priority is to find the lowest common denominator and please everyone. Which results in nobody getting what they actually want. YouTube doesn't have those limitations - you'll find in-depth content for any kind of niche interest and I welcome it.
I can only assume that traditional TV is even less interesting to today's teenagers than it is to me, someone who grew up with it.
