A hundred years ago, radio was definitely becoming a phenomenon, as evidenced by making the cover of Popular Science, November 1922.

The magazine contained ten commandments for the radio fan, authored by Jack Binns, described by the magazine as America’s most popular writer on radio. Many of the commandments are common sense, such as “learn how to use your tuner properly,” although most are outdated, such as “do not use a loop aerial with a crystal detector.”

The second commandment admonishes the reader not to make the ground connection with a gas pipe, but it’s not for the reason you might think. It turns out that gas pipes are insulated at certain points, so it just wouldn’t work very well.
