In one study, “Radio outperforms Newspaper nearly 14 to 1.”

From Roy Williams, the “Wizard of Ads”:

If you (1.) make exactly the same offer on radio as in the newspaper, and (2.) spend exactly the same amount of money with each media, (3.) across precisely the same span of time, radio outperforms newspaper nearly 14 to 1.

Roy adds:

But the greater question remains, “Why has there been no scientifically controlled test?” I ask the advertising agencies spending all those billions, “Why has there been no scientifically controlled test?” I ask the major advertisers of America, “Why has there been no scientifically controlled test?”

When you want to conduct that test, call me.
