This week on Under The Influence
A Matter of Time:
The History of Commercial Lengths

This week, we look at the history of commercial lengths. From the very first 10-minute radio commercial in 1922, to five-second commercials today, the length of ads has changed dramatically over the decades. But it’s not the changing lengths of commercials that’s so fascinating. It’s the reasons why.
