70's 80's and especially 90's had so many more sci-fi shows on tv than now. Granted, many of them were not good, and plenty were crap, but at least it was on TV. The reason is that it is much cheaper to commission a realtity TV show, and even easier to get the viewers. That is why the Nineties was a golden age for TV in sci-fi and fantasy. That was an awesome decade be a geek.
