48 years ago today: Will FM be dominate by 1981?

October 26, 1974 Billboard magazine reports indications that FM stations may be posed to make a profit by 1976 and possibly overtake AM in popularity by 1981. The notion is based on a 1963 Harvard study titled "The Future is FM". It's also expected that AM/FM car radios will overtake the amount of AM only car radios by 1980.. (This updates the prior predictions that FM would overtake AM by 1975).


All very interesting but the most curious statement was "If the all-channel bill is enacted, AM automobile radios will no longer be manufactured."[/b]

I have no familiarity with what the "all-channel bill" was but apparently it wasn't passed.
