Offline advertisers will no longer be content to be told that their radio ad will be heard by a potential audience size or demographic. Instead, they'll come to expect detailed reports and accountability. They'll want to know how effective the radio ad was and whether it resulted in new business. The same level of accountability that search marketers have been held to will now apply to traditional advertising. Expect the skills learned by those search marketers to be in very high demand.
