The Adventures of Rocky and Bullwinkle and Friends (commonly referred to as simply Rocky and Bullwinkle) is an American animated television series that originally aired from November 19, 1959, to June 27, 1964, on the ABC and NBC television networks. Produced by Jay Ward Productions, the series is structured as a variety show, with the main feature being the serialized adventures of the two title characters, the anthropomorphic flying squirrel Rocket J. ("Rocky") Squirrel and moose Bullwinkle J. Moose. The main antagonists in most of their adventures are the two Russian-like spies Boris Badenov and Natasha Fatale, both working for the Nazi-like dictator Fearless Leader. Supporting segments include "Dudley Do-Right" (a parody of old-time melodrama), "Peabody's Improbable History" (a dog named Mr. Peabody and his boy Sherman traveling through time), and "Fractured Fairy Tales" (classic fairy tales retold in comic fashion), among others. The current blanket title was imposed for home video releases more than 40 years after the series originally aired and was never used when the show was televised; television airings of the show were broadcast under the titles of Rocky and His Friends from 1959 to 1961 on Tuesday and Thursday afternoons on ABC (and again in Canada in 1963), The Bullwinkle Show from 1961 to 1964 on Sunday evening and then late Sunday afternoon on NBC, and The Rocky and Bullwinkle Show (or The Adventures of Rocky and Bullwinkle) as repeats from 1964-73 on Sunday mornings on ABC and in syndication following this.
