About The Radio
This is a radio that was present at the very beginning of the radio revolution. Experimental radio broadcasting and home built receivers had existed for many years but 1921 was the year that radio started down the road to commercial success. In November of 1920 Westinghouse began station KDKA, at least partly as a marketing tool to sell radios. In 1921 they marketed the first factory built radio, a crystal set called the Aeriola Jr.. Later that year the 1 tube Aeriola Sr. was introduced. These sets opened up radio to people who did not wish to build their own receivers.
