Officially called the Academy Awards, the Oscars are an annual award ceremony for the film industry. The Oscars were first held in 1929 in Hollywood and first televised in 1953. In 1941, the Oscars began to use a sealed envelope that contained the names of the winners. During World War II, the statue used for the Oscars was replaced with plaster until after the war was over. Since the beginning, the trophies used for the Oscars have been handmade in Illinois. To ensure that the names of winners are not leaked before they are awarded on stage, the plaque at the bottom of the Oscar statue is not inscribed until after the ceremony.
