I've been a long time user / supporter of Pandora Internet Radio.  I don't want to be one of those "I used them before anyone knew about it types…", but in this case I think I did.  I stumbled upon their site a long, long time ago and a quick check of the station I listen to most on their shows I created it in 2005…

Anyway, back when I started using Pandora, it barely showed advertising, and when it did, it appeared it was doing so with some cool CSS tricks, but nothing targeted or relevant to me.

Today, I noticed that I was getting served ad content for Fontbonne University.  Impressed, I grabbed a screenshot (click to make large).  Why is this impressive?  Well, Fontbonne is in my hometown of St. Louis.  This could just a coincidence, but I think it's probably using geo-targeted ads.  I hope so.  If so, Pandora has come along way since they were showing Jamieson ads (and from my fuzzy memory – nothing else) back in 2006. 

If you're a regional marketer, I strongly suggest you considered using geotargeting to reach your audience.  It's usually less expensive and more effective.  I think I'm going to have to talk to them about one of my clients and find out.
