In 1921 Secretary of Commerce Herbert Hoover, who was charged with what meager regulation of the airwaves there was, called radio “an instrument of beauty and learning.” Waldemar Kaempffert, who, as editor of Scientific American, had followed the beginnings of the technology, in 1922 imagined “a radio mother … crooning songs and telling bedtime stories” while “some future Einstein” could elaborate his theories “to a whole world with an ear cocked to catch … his voice as it wells out of the horn.” M. P. Rice, manager of General Electric’s pioneering station in Schenectady, New York, hoped in 1922 “that the power to say something loud enough to be heard by thousands will give rise to the desire to say something worthwhile.”

And indeed, to the growing audience, the sounds that could be discerned above the squawks, screeches, hums, and cracklings of the ether were pure enchantment. The sports columnist Red Barber listened for the first time in 1924, at the home of a high school friend in central Florida. “A man … in Pittsburgh said it was snowing there. … Somebody sang in New York … a banjo plunked in Chicago … it was sleeting in Atlanta.” Barber walked home at dawn filled with “intimations of a new life … I was excited completely.”

So were millions of others as they braved an ear-rending racket on primitive earphones. Hundreds of manufacturers leaped into production, but most audio fans in the early 1920s built their own sets from a chunk of germanium crystal hooked to a coiled copper wire, both attached to a “breadboard.” The most expensive component was the headset, at $1.98; families often would place it in a soup bowl and cluster with their ears close to this primitive loudspeaker. What they heard was “ AWK RAACK … hello out there … hello ouBriee … crackle … snap … weee … this is … ROAR HISS STA tion 8 xk CRASH -hiss … ROA rrr … pop.…”

The transmitters were equally crude. The first microphone at WLW in Cincinnati was a huge morning-glory horn eight feet long and three feet across. “You shouted into the big end,” an announcer recalled, but to be sure of being heard, “you stuck your head halfway down into it.” Phonograph music was transmitted “by putting the morning-glory horn of the phonograph player against the morning-glory horn that was the microphone.” Similar contraptions were the rule at most of the stations, which erupted, like measles, across the American landscape in 1922. At the beginning of that year there were 28 stations, by the end, 570, all operating on just two frequencies. Total confusion was averted only because most of them had little power—twenty to fifty watts—and none of them operated full time. During the next two years, however, the situation degenerated into complete chaos. Some
