AM radio broadcasting was created in the early 20th century and it quickly became the main entertainment source for most people in the United States. FM radio broadcasting would be created about 30 years and would slowly start to over take AM radio.

Radio has always been a great opportunity for companies to advertise their products to consumers. While television and the internet has swooped in lately to take some of the advertising pie away from radio broadcasters, it continues to be a very lucrative medium to this day. Radio advertising was never more prominent, however, than it was in the 1940s.
