Who commercialized radio by broadcasting movies and sports scores?

Answer 1

We've never heard a movie broadcast on radio ... and we don't believe it would

be too successful ... and the inception of sports scores wasn't the big move that

commercialized radio.

The big move that commercialized radio happened on the occasion of about the 100th

time a businessman approached the operator of a radio station and said "I'll pay you

money if you'll read this information about my product during your broadcasts", and the

operator of the radio station finally, for the first time, said "OK".

It didn't happen right away. For the first several years of regular, scheduled

radio broadcasts, the concept of advertising on the radio was regarded with

the same wholesome respect as the concept of a Turkish brothel in Topeka,

Kansas. But in our time, having seen how easily we could come to accept it

as a normal part of broadcasting, they quietly dropped the voluntary limits

on the number of advertising minutes in an hour of radio.
