While the nuclear threat of the Cold War prompted the dedication of a national broadcast frequency, it wasn't until 1958 that the system was first used for weather alerts.However, AM Stereo broadcasts are still conducted by several DFW stations today, and Kahn Communications has recently unveiled a improved system, "Cam-D," which might create a resurgence of interest in AM broadcasting in the future.Also in the late 1980s, The FCC decided to extend the AM band to 1710 k Hz.Whether you knock AM radio today for its relentless static or its lack of music, this is where it all began.
