Have you heard? Google Adwords Radio Spots in Test

Mighty G is testing with a small group of Adwords clients radio spots on conventional radio (non-net) stations all over the country.

Pricing info is murky (surprise) and it appears you'll not be able to specify a station by call letters (surprise), but you can try to run based on city and format and time of day.

It is invitation only and only for select existing Adwords customers.

Blog post by G is here.

Murkey answers to common questions.

this topic was just posted in another thread

 

Missed that - perhaps it was the thread title: Update in AdWords?

 

Yea, the other thread didn't exactly have a descriptive title.

 

Where can I find further information?

 

You could start with the two links in the first post.
