Initially, "Jeopardy!" was relegated by managers of some television stations to unpopular time slots, and it was not unusual for both "Jeopardy!" and "Wheel" to air either non-consecutively, on different stations, or even against each other. However, the new version built upon early ratings successes in Cleveland and Detroit, where it was slotted in the same 7:00–8:00p.m. block (the Prime Time access hour) in which "Wheel" also appeared. Coinciding with the peak of popularity for the board game "Trivial Pursuit" and the installation of electronic trivia games (e.g. NTN Buzztime) in pubs and bars, "Jeopardy!" was slowly becoming a major success despite some markets still airing it in unfavorable time slots. One such market was New York City, the largest in the United States. There, King World sold its new show to WNBC, which had been the flagship of the original "Jeopardy!". When it premiered in the fall of 1984, "Jeopardy!" initially aired at 1:30a.m. on WNBC, following "Late Night with David Letterman".
