text: At the time, and like its major competitors, WABC aired an hour of local news at 6:00 p.m. and followed it with their Network's national newscast, in this case World News Tonight, at 7:00 p.m.. The 7:30 p.m. slot was filled by a syndicated revival of Hollywood Squares, hosted by John Davidson which debuted in the fall of 1986, and was performing well for WABC against the immensely popular Wheel of Fortune on WCBS. Seeing those ratings, WABC thought it could draw equal or better ratings with Jeopardy! in the 7:00 p.m slot. ABC did not require its stations to air World News Tonight at a specific time, giving WABC the freedom to make the move if it wanted.
  On December 15, 1986, the same day Oprah moved to 4:00p.m., WABC reduced the 6:00p.m. broadcast of Eyewitness News by 30 minutes and moved World News Tonight to 6:30, with Jeopardy! airing at 7:00 and Squares following it at 7:30. To alert viewers to the timeslot changes, WABC launched an advertising campaign entitled "Prime Time Begins At 7 On 7". In addition, WABC filled part of Oprah's vacated 10:00a.m. slot with a repeat of the previous evening's broadcast of Jeopardy! until September 1987. The move produced a ratings win in both the 6:30 and 7:00p.m. time slots, as World News Tonight also benefited from the switch; this, along with the rise of WABC's Eyewitness News in the New York ratings books, paved the way for WABC to become the most-watched television station in the New York market.
