WRIST RADIO (Dec, 1953)


DICK TRACY, the famed comic-strip detective character created by cartoonist Chester Gould, has been using a wrist radio for years in his fight against crime. Now the wrist radio is becoming a reality and Sylvania Products, Inc., has proved it by developing the tiny transmitter shown here. But it can’t receive signals such as Mr. Tracy’s. A separate, larger unit is used. This little radio has been made possible by the transistor, a tiny crystal device, which promises to expand greatly the field of electronics by making possible the manufacture of tiny electronic sets.

    This also shows us one important concept. It’s far easier to transmit something than to recieve something.
