@@TheBrooklynbodine it was owned twice by NBC - the first time, it was for eight years, from 1948-56 (as WNBK, originally on channel 4 prior to 1954), before it was reacquired by NBC in 1965 (for 25 years).
Never knew it was twice NBC-owned. I do know that from 1956-65, it was KYW and Westinghouse-owned. In 1965, NBC and Westinghouse swapped stations in Philadelphia and Cleveland. WKYC (Cleveland) was KYW-TV during those years. Since 1965, KYW has been in Philadelphia. Interestingly, both stations are on Channel 3.
