The Adventures of Rocky and Bullwinkle and Friends is the blanket title for an American animated television series that originally aired from November 19, 1959, to June 27, 1964, on the ABC and NBC television networks. The current blanket title was imposed for home video releases over 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, The Bullwinkle Show from 1961 to 1964, and The Rocky and Bullwinkle Show (or The Adventures of Rocky and Bullwinkle or The Adventures of Bullwinkle and Rocky) in syndication. 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 Rocky and moose Bullwinkle. The main adversaries in most of their adventures are the two Russian-like spies Boris Badenov and Natasha Fatale, both working for the 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.
