I'm WAAY down on watching old-school (i.e. network or cable) TV, but my TV is on just as much as it was 25 years ago.
I cut cable almost two years ago. There are slivers of compelling content that I miss, but not enough to pay for the package. Cable TV will have to change to an a la carte model or I'll never go back.
As for broadcast TV, I don't even really know what's on network TV anymore. The only recently produced network TV show that was compelling in the last five years was "The Cosmos" on FOX (which I heard about online) - and I didn't even watch it when it was broadcast live. I watched ALL of the great show on Netflix Streaming instead.
Sometimes I'll watch some classic TV shows on channels like MeTV (Twilight Zone, etc.), but those channels test my patience for commercial breaks because I'm not shopping for LifeAlert, denture cream or life insurance. If they're on Netflix Streaming I watch them there instead.
Typical TV watching evening in 2015:
Turn on TV... Watch 10 minutes of evening news, if that... Fire up Youtube app and watch about 30-45 mins. total, browsing popular videos that look interesting before browsing to my favorite YT content (AsapScience, Crash Course, Screen Junkies, HowItShouldHaveEnded, etc.), clicking on "Skip Ad" after 5 seconds (I hate those ads and will not watch them and will hit "Back" if I can't skip the ad)... Turn off TV... Come back later if there's time and fire up Netflix Streaming and browse good content and/or the occasional decent movie choice...
