"After the theatrical Popeye cartoon series ceased production in 1957, Bluto's name was changed to Brutus because it was incorrectly believed that Paramount Pictures, distributors of the Fleischer Studios (later Famous Studios) cartoons, owned the rights to the name "Bluto". King Features actually owned the name, as Bluto had been originally created for the comic strip. Due to a lack of thorough research, they failed to realize this and reinvented him as Brutus to avoid supposed copyright problems."
