The quality of typical network broadcast television in the USA is abysmal.
What passes for situation comedy today is so poorly acted, written and edited that it's not worth your time, even if the situations are clever.
The acting is wooden and not believable. The commercial interruptions are so invasive that even muting the audio is tiring.
Late night talk shows are liberal gush-a-thons, with such sophomoric humor that they are predictably boring. Colbert doing the "Trump Voice" isn't the least bit funny, but rather a sad commentary on how little creativity his team has.
Video on demand over the Internet is less costly and more focused and useful than cable television (except for live broadcasts) and may soon even include enough live events to supplant cable.
Many of these production companies become insulated self-worshiping isolated islands where eventually the leadership, like the deluded emperor, has no clothes. They feed on their initial success and lose their creativity, stringing along sponsors as long as possible until they are cancelled.
I worked in non-commercial television for 13 years, and saw much of this play out in their context. At least I could keep our news team on the "straight and narrow" by often calling them on poor 2nd Amendment related reporting before it aired, getting the producers to pull or delay stuff until it was accurate. Believe it our not, there were a number of gun rights people on our staff, and the producers actually wanted to be balanced. This is unlike NPR radio and their agenda fueled lies, or some of the national level producers at PBS.
