By the early 1970s, however, listeners were slowly discovering the FM band and migrated to it for its static-free, stereophonic broadcasts; by 1978, FM overtook AM as the most popular band.Attempts to revitalize AM have netted little; AM Stereo was proposed in 1958 and introduced in 1982 to big fanfare; many car manufacturers began to integrate AM Stereo into their radio units, and KRQX-570 became the first local AM Stereo station in 1983.
While KLIF posted incredible ratings during the 1950s and 1960s, others like KRLD and WBAP found successful programming niches that catered to older audiences.Whether you knock AM radio today for its relentless static or its lack of music, this is where it all began.The early 20th century brought the first radio stations to the Dallas-Fort Worth area: KFJZ (with roots dating back to 1917,) WRR (in 1920,) WPA, WBAP and WFAA (all in 1922,) and the rest is history (well, almost!) AM started out as a freewheeling, 'throw up a transmitter and go with it' gamut of radio waves in its earliest days, with a couple of assigned frequencies (833 kc [primarily news and weather] and 618.6 kc [primarily music.]) and virtually no rules to allow a fair distribution of the dial for broadcasters.(By mid-1922, all five DFW stations agreed to a timesharing plan on each frequency.) November 11, 1928 was declared "National Frequency Allocation Day," when the Federal Radio Commission (FRC, predecessor to the FCC) brought organization to the dial by assigning dedicated frequencies to the strongest stations, and culling out many of the small-time opportunists who weren't serious about broadcasting.
