Jeremy Mayes participated in a test of Google print ads and found the results less than impressive, and concludes:

I will say that based on the results form the test the newspaper ads would have to be pretty inexpensive for this model to work in certain markets, and, tracking results at the level in which PPC managers are accustomed too isn’t there – or it least it wasn’t there for me.

I think overall there is potential for this program – pricing, trackability and ease of setup/scheduling will be three of the biggest issues from what I can tell.
