Some extra information regarding the history of Radio Broadcasting.

1. A Brief History of Radio Advertising
The first recreational Radio broadcast occurred in 1906, Ships at sea could hear Reginald Fessenden
playing "O Holy Night" on his violin and then reading a verse from the Bible.
From then on Radio continuously expanded in popularity
throughout the early 1900’s, however, broadcasting was (and
still is) very expensive. In order to keep up with the financial
implications of running a radio station, the idea of selling “toll
broadcasting” to advertisers, in which businesses would
underwrite or finance a broadcast, in exchange for being
mentioned on the radio.
WEAF of New York is credited with airing the first paid radio commercial, on August 28, 1922, for the
Queensboro Corporation, advertising an apartment complex. This trend continued with the
expansion of radio until the end of World War 2. With television overshadowing radio, there was a
massive overhaul of audiences moving from radio to television.
Yet even today, with 95% of the
population listening to the radio every
week, radio is far from dead.
