in a sound similar to WABC's during its Top 40 heyday. Two weeks later, on March 23, 1987, Soupy Sales had found out that there were plans to end his show; at that point, he walked off midway through with Dale Parsons finishing the show. Weekender and assistant programming director Jim Collins moved into that time slot with a gold-based music intensive show on a temporary basis. Then, on April 6, 1987, a couple weeks after Soupy Sales left, his former sidekick Ray D'Ariano moved back into the 10 am to 2 pm weekday time slot, but was now playing 1955–73 oldies while focusing on 1964–69. His show was music intensive, playing about 12 oldies an hour. In the summer of 1987, WNBC considered going all oldies, running The Time Machine full-time, with the exception of Knicks and Rangers games, and Imus in the Morning. Instead, they increased the amount of oldies programming, but not on a full-time basis. Therefore, WNBC modified their format, keeping Imus in the morning, playing a few AC cuts and a couple oldies an hour with his usual talk. Alan Colmes continued hosting the afternoon drive talk show, but dropped music altogether. In evenings, Dave Sims continued with sports talk along with Knicks and Rangers games. The Time Machine remained on overnights, but was now expanded to full-time on weekends with hosts Dan Taylor (laid off from WHN when they became WFAN), "Big" Jay Sorensen, "The Real" Bob James, Jim Collins, Lee Chambers, Dale Parsons, Carol Mason and others. Ray D'Ariano continued his midday weekday oldies show, but was not part of the "Time Machine" programming. His show had newer WNBC jingles, no echo sound effects, and slightly softer songs. From the Summer of 1987 to the station's demise on October 7, 1988, WNBC's format was classified as Adult Contemporary, but they only played adult contemporary cuts during Imus's show. The actual format was block programming featuring AC and talk in morning drive; all-oldies on Middays, overnights, and weekends; talk on weekday afternoons; and sports talk weekday evenings and whenever the Knicks or Rangers played a game. It was difficult to classify WNBC's format at that point. The launch of sports radio on 1050 At 3:00 p.m. on July 1, 1987, Emmis Communications-owned WFAN signed on at 1050 kHz, replacing country music station WHN, and billing itself as the world's first 24-hour-per-day sports talk station.
