We are currently experiencing the Golden Age of Geek, where you can literally turn on almost any channel and get some high quality sci-fi, fantasy or even comic book TV shows. I can tell you, it didn’t always used to be that way.
Growing up there was the big two — Star Trek and Star Wars. The Trek you could find almost anywhere on TV, while Next Generation is still one of my favorite shows everyone was hoping for another Star Wars. There was one sanctuary, a channel called Sci Fi (before it turned into SyFy) and it played the classic science fiction; Buck Rogers, Lost in Space, Twilight Zone and the all time classic Battlestar Galactica. While I was aware of the series there’s a big difference to actually watching it.
