This is the TV channels' (and cable companies') worst nightmare. And I'm sure it's gradually happening everywhere.
I'm 26, so I'm on the tail end of the generation that watched any TV in the pre-internet-streaming age. My parents never had cable growing up, but I did watch some linear over-the-air TV as a kid. Most of it was PBS though, so no commercials. Then around age 10, I started watching a few non-PBS shows (still OTA) with commercials, mostly dumb stuff like Who Wants To Be A Millionaire, and the commercials really bugged me but I tolerated them because I was just a stupid kid that wanted to watch TV. At 15 (2006) I discovered the wonderful world of Bittorrent, and pretty much stopped watching live TV or commercials of any kind right there. I was "binging TV shows" (like House) before it was a thing. As an adult, I've since switched to legal commercial-free streaming options (as they became available). Post-2006, I can only think of a handful of shows (and definitely not every episode of each) that I've made any effort at all to watch live (at a friend's house if on cable), with commercials, and it's always jarring and awful, so only worth it for the best of shows (like the Breaking Bad season four premiere brought to you by the same Jimmy Fallon Capital One commercial played repeatedly). I do watch Game of Thrones "live" right when it's available on HBO Now, but there aren't commercials, so it doesn't really count.
Now, we use Netflix and Amazon Prime (and HBO Now during Game of Thrones season). We also have an antenna, but that gets used for one particular current show, and put away at other times (it's ugly). I've never watched "the news" on TV, I've always just read the news online.
I haven't turned on a TV channel "just to see what's on" since the PBS days as a kid. I'm sure if I was <10 right now, I'd have no real concept of TV channels.
