Smokey Bear has been the symbol of the US Forest Service for years. In 1969, Rankin-Bass and ABC decided it'd be a good idea to have kids get to know Smokey by making him a cartoon star. Jackson Weaver, who'd been the voice behind the bear in commercials, was the star here, too. Wmlocher uploaded the open:
Unfortunately, not enough kids were interested in seeing Smokey on a weekly basis, and the series was shunted off to Sundays for its 2nd & final season. The next year, Rankin-Bass would fill the vacant space with adaptations of The Reluctant Dragon & Mr. Toad, but that would also result in failure.
