The Howdy Doody Show, hosted by "Buffalo Bob" Smith, was a groundbreaking children's television show that aired from 1947 through 1960. Howdy Doody was a blue-eyed, red-haired, freckle-faced marionette, whose name originated from the expression "howdy do," a variation of the greeting "How do you do?" Each episode of the show began with Buffalo Bob asking the audience, "What time is it?" to which they would enthusiastically respond, "It's Howdy Doody time!" Howdy Doody is now on display at the Smithsonian's National Museum of American History.
