I thought that WTAM was a new set of calls. When I was dx-ing, it was WWWE and I just assumed it always had been. It sounds like they brought them back. Is that true?
The history of this station is more complex than just a simple listing of calls and years would suggest. WTAM was the heritage call under the station's first owners, a battery company and then NBC itself. In 1956, NBC swapped WTAM/WTAM-FM and WNBK(TV) to Westinghouse for KYW/WPTZ(TV) Philadelphia. Westinghouse didn't want to make the swap but was forced into it under the threat of losing its lucrative NBC affiliations in several other markets, and a lawsuit ensued that ended with a forced swap back in 1965.
Westinghouse had moved the KYW calls to Cleveland, and moved them back to Philadelphia in 1965. NBC wanted to keep calls that were similar, hence "WKYC" (the calls that survive on TV in Cleveland). WKYC radio was sold to new owners in 1972 and had to change calls, which is where WWWE came in. It was Jacor that changed the calls to WTAM in 1996, and they made the claim at the time that there was no conscious effort to return to the 1923-1956 heritage, just to find something with "AM" in it.
Knowing the people who were in charge of Jacor when the switch was made, I say there's no way they were unaware of the heritage callsign, and that the move was very deliberate.
I'm pretty sure there's no other former I-A clear channel on the AM dial that's changed identities as much as WTAM. New York's 660 probably came closest, with four call changes (WEAF to WNBC in 1946, WNBC to WRCA in 1954, WRCA to WNBC in 1960, WNBC to WFAN in 1988).
