An anonymous reader writes "Google's tech-heavy solution to advertising has worked wonders on the internet, and made it a friend to bloggers everywhere. The low-tech nature of traditional radio, though, has caused some conflicts with Google's radio ad service. The impersonal nature of online ads are very different than the one-on-one personalized service that radio advertising normally uses. While Google ads are running on some 700 radio stations, that's a very small part of the market. They are committed to improving, but onlookers think it will take a change in pitch. 'Whether Google can succeed in radio "is questionable, because you do need relationships with radio stations to give you something of value. If you don't have radio-focused personnel...you'll get the low-hanging fruit but may not be able to grow the market," said Maribeth Papuga, senior vice president and director of radio buying for Media Vest, a part of ad firm Publicis Groupe. "Their challenge is going to be having a broad enough list of markets and stations to make it a viable enough player on a national scale."'"
