Initially the Discovery Channel was about science. In the beginning they filled in some time slots with programs about UFOs, the Loch Ness Monster and lots of old science and speculative TV specials from previous decades; however, now things have changed a lot. Junkyard Wars and even MythBusters can at least be considered slightly scientific, but shows like Cash Cab, Dirty Jobs, American Chopper, Monster Garage and a few other are more mainstream. They eventually made another channel called Discovery Science which eventually became the Science Channel.
I don’t watch a lot of TV, since it’s something I just now began to really notice. But it makes me wonder if the “reality-based”/pseudo-documentary TV trend has gone too far. At least during the talk show TV trend days, you couldn’t modify them into any other kind of genre to show on other TV stations.
I preferred the Discovery Channel when it was boring to everyone else. But in order to capture more of the general audience they sacrificed their niche audience. Which reminds me, I saw a medieval-based fantasy B-movie on the SciFi Channel recently. I’m not sure how dragons and swords are related to science fiction, but I guess they ran out of programming.
I just hope the History Channel doesn’t end up like Discovery, fortunately it’s not owned by them. Digging for the Truth and Mail Call aren’t too bad, but if they continue too much down that path, they will lose their niche audience.
