Jeopardy! is an American television game show created by Merv Griffin, in which contestants are presented with trivia clues in the form of answers and must phrase their responses in the form of a question. The show has experienced a long life in several incarnations over the course of nearly a half-century, spending more than 12 years as a daytime network program and having currently run in syndication for 39 seasons. It has also gained a worldwide following with a multitude of international adaptations. 1964–1975 Original series (1964–1975) The original Jeopardy! series, hosted by Art Fleming, premiered at 11:30a.m. Eastern (10:30 Central) on March 30, 1964, originating from studios at the NBC headquarters in New York City's 30 Rockefeller Plaza. NBC moved the program to 12:00 noon Eastern (11:00a.m. Central) after 18 months, making it accessible to businessmen coming home for their lunch break or else watching it on restaurant or bar sets, and college students departing their classes for the day watching it on student center or dormitory sets. These two constituencies, who ordinarily did not have the time or interest to view other daytime programs, made the show a runaway hit, propelling its ratings to second place among all daytime game shows by the end of the decade—second only to its immediate lead-in, The Hollywood Squares. The show had practically no trouble whatsoever against soap operas such as Love of Life and Where the Heart Is on CBS and mostly sitcom reruns on ABC. In 1973, Lin Bolen, then Vice President of Daytime Programming at NBC, began eliminating longer-running game shows from the network in an aggressive attempt to bolster ratings among women aged 18 to 34, a desirable demographic to advertisers on daytime programs of that day; Jeopardy! had not performed especially strongly among those viewers, despite its overwhelming success among men and young people. Refreshing the daytime lineup became especially imperative to Bolen when CBS launched a surprise success in the soap opera The Young and the Restless at 12:00p.m. EST (11:00a.m. CST) in March 1973, drawing away younger audiences in particular. Although Jeopardy! continued to produce high ratings in the 12:00 noon time slot (also against the ABC revival of Password), Bolen moved the game to 10:30a.m. Eastern (9:30 Central) on January 7, 1974, putting it up against CBS' The $10,000 Pyramid, to make room for Jackpot!, a stylish, youth-oriented riddle contest hosted by Geoff
