When The WB and UPN merged to become the WB, the leftover stations apparently turned into a network lamely called myNetworkTV. According to Wikipedia (and I remember this when they started up), they originally began as the place where English-language telenovelas started up; they didn't catch and, quite frankly, I am never sure what these stations are for except as literal way-stations from one of out PBS affiliates to the other.
Except that occasionally these networks show some pretty funky movies for network television.
I haven't been watching too much prime-time network TV, but it's fun to do while folding laundry. About a month ago, I remember channel surfing and discovering to my amusement that Lars von Trier's Dancer in the Dark was showing. Thinking that only PBS would have the nerve to show a long, difficult film with non-stop handheld camera punctuated by musical numbers all featuring Bjork, I was truly shocked when all of a sudden a commercial for fast cash appeared.
Tonight, they appear to be showing The Rocky Horror Picture Show.
Who is programming this stuff? This is great.
