They really are taking over! Google is going to begin offering ads on the radio to some of its AdWords customers; they will be targeted very specifically for customers. Is there anything left this company doesn't do? From Information Week:

Google has completed the integration of the online radio advertising platform it bought when it acquired dMarc Broadcasting for $102 million earlier this year and has begun testing Google Audio Ads for a select group of its AdWords advertisers.

Google aims to bring "efficiency, accountability, and enhanced ROI to radio advertising by providing advertisers with an online interface for creating and launching radio campaigns," according to a blog post attributed to "Josh M., a member of the Google Audio Ads team."
