in august 1964, after a nearly eight-year-long investigation, the fcc ordered a reversal of the swap. nbc appealed the ruling, extending the ordeal by another year, but to no avail. westinghouse was also allowed to keep the cash compensation from the original deal. when westinghouse regained control of the philadelphia stations on june 19, 1965, it restored the kyw calls to the radio station and renamed the television station kyw-tv. and in a reversal of nine years prior, both nbc and westinghouse relocated various personnel between both cities.
