From Fledgling to Floundering to Flourishing: A history of FM Broadcasting in Michigan from the 1930s through the 1960s

"During the 7 years of its existence, WWJ-FM, Michigan's first FM station, has made a deep and lasting impression on the listening habits of Detroiters. So conscious are they of WWJ-FM's leadership, that the thousands of FM sets in the Detroit area are almost automatically tuned to WWJ-FM regularly. This impression value will produce gratifying results for WWJ-FM advertisers during the golden FM era ahead, in the prosperous Detroit market, where steady employment of more than a million workers is virtually assured for years to come, supplying America's most in-demand product... shiny new cars!"
- WWJ-FM Ad, FM Business Magazine, September 1947

"Had it not been for television's simultaneous birth, FM might have captured the public's fancy with its high-fidelity and static-free claims, many of its friends insist. Certainly the glamour of visual radio has held the postwar spotlight in the populous parts of the nation, with FM unable to stir violent public response to its claims."
- Broadcasting Magazine, October 9, 1950

This 1946 Zenith table radio was built as FM was undergoing its wrenching and controversial move from the low to high band. It tunes both Pre- and Post- War FM bands. The selector is labeled AM/FM 40/FM 100. Depending on availability of power and space, some pre-war stations, including Detroit's WENA (W45D) operated on both bands during the transition, while others like Detroit's WLOU (W49D) ended low band operations when they switched to the new 100 MHz band. A subsequent change in frequency spacing caused yet additional shuffling even after stations relocated to the new band. In 1947, as the transition was nearing completion, only 3,000 high band radios were in use in Detroit compared with over 21,000 now obsolete low band sets (Source: FM Business).

1969 "California Radio" Poster from WJR-FM Detroit. This syndicated programming was from Bill Drake who took the stellar success he enjoyed at AM stations like Detroit's CKLW and made it part of an explosion of formats to hit the FM band. Beginning in the mid-1960s broadcasters in cities with more than 100,000 people were required to meet an FCC mandate to offer separate content on FM, ending the simulcasting of AM programs which, while quite rare in the 1940s, became ubiquitous during the 1950s. Another Bill Drake FM format offered at the same time, "Hit Parade '69", was heard in Michigan on WSBM in Saginaw. From the author's collection
