I was a teenager in 1991. And my experience of the early ’90s bore little resemblance to the media of the day, or at least any of the media that I saw. Those idealized views of the world were always a phantom for most, but by the 1990s it was a phantom of a world which was already long gone.
For pretty much all of the 20th Century, western entertainment was very heavily geared toward the sensibility of middle-class whites, due to that category of people being most able to access and afford mass-culture entertainment. There were exceptions, of course (witness conservatives bitching about Sesame Street’s “excessively liberal” treatment of race for its entire existence, since 1969!) but it was largely seen as justified, from a purely economic perspective. There was a gradual increase in “nontraditional” audiences of various sorts over the 1980s when mass-market media became much more accessible, but it wasn’t until the very end of the 1990s that most media producers realized just how much of an untapped market there was out there, and even then most of them were cautious about backlash from middle-class whites for another decade.
Now that media markets are highly fragmented, and on-demand access available to virtually everyone, there is little economic justification for not catering to a wide variety of audiences - and most of those audiences are going to want their “politics” (the political is the personal) reflected to some extent. Demanding that media cater only to you used to be a privilege; now it’s an entitlement, and a particularly unrealistic one at that.
