PBS is also the home of “Austin City Limits,” one of the best music television shows bar none (now that MTV and VH1, as of last year, really don’t show music anymore). You can’t find a show like ACL on cable. You just can’t. For those of us who don’t live in a town with decent college/non-commercial radio station, Austin City Limits fills the gap quite nicely.
As for opera, for those aren’t aware of this - the AMC movie theater chain has for quite some time now simulcast operas from around the world in their theaters. And, whenever I have been at a movie and see it there, the theater showing the opera is just as full as the theater showing the movies. So, obviously, there’s really no question that opera already is mainstream.
