In the early-1970s, an entirely new base of operations for color television and updated news film processing were constructed as part of the new Park City Center in that city. WSBA simulcasted WLYH's newscasts until the arrangement ended in 1983 with the former severing ties after becoming WPMT. In September 1992, the station discontinued its 11:00 p.m. newscast in favor of airing first-run syndicated programming in the timeslot; this left the existing half-hour 6:00 p.m. edition of "Action News" as the only newscast that channel 15 offered for the remainder of the news department's existence.
