When did the Boy Scouts national popcorn sales program begin?

The Weaver Popcorn Company (makers of Pop Weaver popcorn) started working with Packs and Troops in Buffalo Trace Indiana in 1979. The idea for councils to sell popcorn spread from there. The Weaver Popcorn Co. began selling their popcorn to the public in tins with the BSA logo until they were asked to stop by BSA national on the grounds that they did not officially sanction the product. Weaver responded by creating a brand that could be marketed exclusively by scouts, Trails End.
