By 1937, radio had long been known as "radio." But if you had been around in the early 1920s, radio was called a number of things-- wireless, wireless telephone, radiophone, and radio telephone. By the mid-1920s, however, the other words had fallen out of use, and radio was in fact only called "radio." What is interesting about 1937 is that FM was beginning to get into the news. In radio's first several decades, all stations were on AM. But in the late 1930s, inventor Edwin Howard Armstrong was demonstrating his new way of broadcasting-- which was generally referred to as "static-free radio"-- since AM signals tended to pick up all kinds of interference from the atmosphere, whereas FM signals did not.
