English: A woman in New York, Rosalind Kendall, playing chess with a friend in Chicago using a two way radio link provided by a Jersey City radio station, published in a 1922 radio magazine. Practical radiotelephone (sound) transmission became possible with the invention of the vacuum tubeoscillator radio transmitter in 1913. By 1922 radio broadcasting was just beginning, radio became a hugely popular high-tech innovation, and a "radio craze" swept the country, inspiring stunts like this. The woman spoke into the cone-shaped horn attached to the transmitter's carbon microphone, and listened to her friend's reply in the earphones.
