The Flintstones were based upon the light comedy used by early sitcoms. The original show aired during prime-time and was geared towards an older audience. Yogi was aimed at kids and that was reflected in the slapstick comedy.
I suspect that Scooby Doo is still an active franchise because it is based around universal themes that make an easier transition from era to era.
