In March 1985, Capital Cities Communications announced it was purchasing ABC, a move that stunned the broadcast industry since ABC was some four times larger than Capital Cities at the time. Some have said that Capital Cities was only able to pull off the deal because WPVI-TV, the company's flagship property, had become very profitable in its own right. However, before the merger could be completed, Capital Cities was required to sell channel 6 and its sister station, WTNH in New Haven, Connecticut, as both stations had a large signal overlap with network flagship WABC-TV. Owning two stations with a significant signal overlap was prohibited by the FCC regulations of the time, similar to the same "one-to-a-market" rule that forced Triangle to split its newspaper/broadcast combination in Philadelphia many years earlier. Capital Cities sought a waiver of the rules to keep WPVI, citing CBS' then-ownership of WCAU-TV locally in Philadelphia and WCBS-TV in New York. The FCC granted the waiver, and when the transaction was finalized in early 1986, WPVI-TV became an ABC owned-and-operated station. A decade later, in 1996, The Walt Disney Company purchased Capital Cities/ABC.
