At Last, A Graph That Explains Scifi TV After Star Trek

In 1970, the gap between shows featuring magic and shows featuring more science-based themes is fairly wide, which may be related to the relative cost of producing the different types of shows; Captain Kirk required pricey sets and a makeup crew while Samantha Stevens just needed a film editor and the ability to wiggle her nose.
