Google has partnered with the first newspaper in Chicago, the Sun-Times to run classified-like ads which fills the newspaper’s remnant space.

Google is running ads in proximity to relevant content. On Dec. 12, for instance, Google ads touting ticket brokers, White Sox apparel and Chicago Bears memorabilia ran in the Sports section.

This move helps Google extend its local advertising reach even though it already displays web search results and PPC ads geographically. If this deal works out, it’s unclear at this point how the pricing would work for such a model and how advertisers can track activity arising from this form of advertising.
