I first ran across reruns of Wild Bill Hickok when they aired on CBN (now Freeform) in the 80's. Back then, of course, Hickok was airing as much as six days a week, but when the series ended its original run in 1958, it was airing concurrently on 2 networks, ABC & CBS, the former on Friday afternoons.
Guy Madison had the title role as Hickok, aided by comedy relief sidekick Jingles (Andy Devine). Basically, this was a typical Western aimed at younger viewers during the period. Sony owns the rights to the series, as it was originally distributed through Screen Gems.
