Regarding "quality" television and "crap" TV: this is clearly an area where individuals' values differ, but my understanding from interactions with people who are involved in the business is that most people use television to "blob out". Another way of putting this is that most people are using TV for entertainment, rather than for education or enlightenment.
Many programmes are purchased from the US, where I know "Pawn Stars" had a significant effect on the character of "factual" or "unscripted" programming because it rated very highly - and still does.
A commercial television company is bound to show programmes that deliver most "eyeballs" to its advertisers. The penalty for failure is severe, which discourages risk-taking. Consequently, the broadcasters tend to be conservative in their approach to innovation: it's very common to find "clones" of a successful series on competing channels.
I've observed that television channels that start out as relatively "high culture" tend to move "down market", since this seems to make more money - partly because audiences increase, and partly because programmes for this market can be made more cheaply (though not necessarily).
There are certainly differences between the US and Europe, for example, where I think governments play a greater role in regulating and financing television.
Television in New Zealand is essentially all commercial and - from my perspective - its programmes reflect this. What's offered may not be to your taste but it seems to be working for the businesses concerned.

I used to make these!

I suppose I like to think of myself as eclectic in my tastes. (Maybe everyone says that.) This piece, however, is pretty hard work. I challenge you to listen to it all the way through.
I think it's how we learn to sing. We hear American accents (which have long been prominent in popular music) and, consciously or otherwise, copy them. It's no longer "American", necessarily; simply part of the genre. I remember a series about popular music on TV years ago, in which one interviewee traced a lot of it back to the Appalachian influence in Country music which, itself, had a strong influence on early Rock and Roll.
I can remember singing teachers (and others) of the 60s and 70s being really disparaging about American accents. (Actually, I remember some people being pretty negative about the Kiwi accent(s) in singing. The word "the", for example, pronounced in a NZ accent, was anathema to one choir conductor. I think that was partly because of what it tended to do to the length of the sung note.)
A similar thing used to happen in theatre with English accents.
One of the best ways to learn is by imitation. In the early stages, we don't know which parts of what we're imitating are going to be most important to us. As we become more confident and experienced, we find our own "voice" (see "mojo" above).
If market forces are important to us, then we might tend to stay with an "American" pronunciation. It does seem to be easy to sell to the "world market" by comparison to other accents.
And I just discovered the sabretoothed vampire. Where have I been?
This might not be your sort of music, but it’s a pretty impressive audience/performer interaction.
