Most people do not “tune out” during the commercial breaks on radio. On average 93% of listeners over the age of 6 years old stay “tuned in” to a station during commercial breaks. Among people age 65+, radio delivers 98% of the lead-in audience when commercials play.
Compare that to only 42% of newspaper readership taking notice of your full page print ad. Or only 36% of newspaper readership reading the Front Page of the newspaper.
