Just a brief note in case you missed it:

Earlier this week Donna Bogatin posted exclusive coverage of just how Google is pitching its radio advertising to advertisers.  She has acquired several images depicting how the Google Audio Ads platform will work.  It's definitely worth a read.

One of the images says "800+ stations signed en route to 5,000+ / 87% US coverage".  If those numbers are accurate, I'm sure we'll be seeing… oh… I mean hearing… these ads in action before too long.
