The first radio commercial was 10 minutes in duration. The ad cost $50.00 when it ran in 1922 on NYC's WEAF. The Queensborough Corporation aired the spot to promote Hawthorne Court, a new apartment complex in Queens. The real estate company urged people to move out of congested urban areas and into the lush new housing complex located near the city limits. This was a bargain for the advertiser as 50.00 in 1922 add up to around 614.00 today.
