If you haven’t yet seen this, Scott Childers gives us an excellent timeline of Chicago’s WMAQ. Scott starts at the beginning: 1922, when it first signed on as WGU. The big 670’s days as a legendary country outlet and flagship station of the Chicago White Sox are covered. “WMAQ’s gonna make me rich!” The short-lived talk format and WMAQ All News 67 are also explained in detail. Finally, the sad demise in 2000 as CBS dumped 78 years of radio history, killing WMAQ and replacing it with The Score WSCR-AM.
Scott covers it all in his Chicago Radio Time Capsule. It’s well worth the read.
