NBC assumed control of WTVJ in mid-September 1987. However, both WTVJ's and WSVN's respective affiliation contracts with CBS and NBC did not expire until December 31, 1988. As a result, NBC faced the prospect of having to run WTVJ as a CBS affiliate for over a year. This did not sit well with either NBC or CBS, and both approached WSVN's parent Sunbeam Television about ending the station's NBC affiliation contract early. However, Sunbeam balked; its owner, Edmund Ansin, did not want to lose NBC's strong lineup of sports programming that year, including the Major League Baseball World Series and the Summer Olympics. Sunbeam also made an unsuccessful play to take the CBS affiliation. NBC did strip nearly all CBS branding from channel 4 and began airing nearly all NBC programs that were preempted by channel 7. In turn, this resulted in WTVJ preempting some CBS programs, with the affected shows airing instead on WCIX. CBS then formally approached channel 6, despite the fact that it would have provided a much weaker signal to Fort Lauderdale than that provided by WTVJ or WSVN. WCIX's transmitter was located near Homestead, southwest of downtown Miami, giving Fort Lauderdale only a weaker, "Grade B" signal. Accordingly, West Palm Beach's longtime ABC affiliate, WPEC, was persuaded by CBS to switch to the network in order to ensure full coverage in Fort Lauderdale and northern Broward County. In August 1988, CBS announced that it would purchase WCIX from the TVX Broadcast Group, which itself had purchased the station from Taft in 1987.
