I'm still going through my old vhs collection and putting it onto dvd and I came across a couple of Batman episodes from when the Scifi channel ran them. As I watched the Superman serial last week I thought of the later tv show and realized that they were really different shows with different impacts, but Superman lasted from 1952 to 1958 while Batman ran only from 1966 to 1968. They both impacted how the culture thinks about superheroes but Superman played it straight and Batman didn't, Superman didn't use his comic book rogues and Batman couldn't have survived without them, Superman didn't bring in Supergirl but Batman brought in Batgirl. So many differences but for many around in the 1960's and 1970's these were the two superhero shows that created the impressions of what superheroes were. Hard to say which of them had the greater impact, even though Batman was flashier.
