You can make a good case that the WHDH callsign has been used continuously in Boston longer than any other.
WHDH first appeared in Gloucester in 1929, but by 1930 it had been moved to Boston. It was used on AM continuously from then until 1994, as well as on FM from the late 1940s until 1974 and on channel 5 from 1957-72.
To clarify: Mugar bought WHDH radio in 1989, looking to add a radio component to channel 7 to better compete against the WBZ radio/TV juggernaut. He put the WHDH-TV calls on channel 7 in the spring of 1990 and moved the AM studios from Stuart Street to the top floor of the channel 7 building at Government Center. (That space had been vacant for almost a decade since WRKO/WROR moved out after RKO sold them.)
Mugar then sold WHDH radio to ARS in 1992; that made WHDH a sister station to WRKO and there was just too much duplication of talk formats for them to both survive. WRKO survived as the talk station and the WEEI sports format moved to 850 from 590 (flush!) in 1994, leaving the WHDH calls only on TV.
But wait, you say - how has WHDH been in use in Boston longer than WBZ? Because the WBZ calls didn't move to Boston until 1931. The Boston station was WBZA from 1924 until it swapped places with WBZ East Springfield.
