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.
