When was that? I'm genuinely asking, since I remember the breakdown from when I was recording TV to my computer and editing out the commercials, as 10 minutes of commercials and 20 minutes of TV show.
Are you mostly watching short videos? I mostly watch videos that are 10+ minutes and I've never had YouTube come anywhere near either the number or total length of ads that I saw on cable or that I see on broadcast TV.
Absurd but true in a similar way: I get a tiny spark of nostalgia on those occasions where a bit of sponsored promotion pops into part of some podcast i'm listening to as a YT video while I do chores. (Ublock running, so no third party ads at least)
The thing about those idiotic third party ads on YouTube, which is so grotesquely annoying is that, unlike TV ads of old, some of then can literally run for dozens of minutes at auto-increased volume unless you go to your device and skip them at some point. That is some particularly shitty nonsense right there.
