Ok, your edit makes more sense. I agree that American TV has way too much advertising and is the worst on that front compared to many other countries. I think your original comment was downvoted because it was just a handful of stereotypes with not much relation to reality.
Also, the shows themselves are generally quite good, it's just the networks that suck. When many Americans think of TV they're thinking of HBO and Netflix and friends, so advertising isn't such a big deal.
That's a matter of interpretation. HBO and Netflix aren't TV, and while perhaps many Americans may interpret these as TV, my perspective is that they're not TV shows, but movie formats.
My main point is that with "regular" TV, if you removed all of the flashback reminders and commercials, you've basically got a 15 minute TV show stretched over the period of an hour with as much drama as can be thrown in so as to keep you sitting there in front of as many commercials as they can squeeze in during that time. It's a disgraceful waste of your time as a viewer.
One of the main purposes of Netflix is to show normal TV shows without commercials, though. And seriously, have you watched anything besides reality TV? The Office? Breaking Bad? Any decently reviewed show in the last 10 years?
