We’re already seeing some of these “evolved” ad networks. Last March comScore reported the emergence of that targeted ad networks like Snap Shots Network and GoFish Networks, companies that have been performing well through specialization. And last week, Burst Media announced the launch of Kiwibox, a teen-oriented ad network. For companies with an aggressive growth strategy, these could make for appealing acquisition targets.

Some companies that could really stand to benefit from these niche, performance-focused ad networks are print media companies. All of them already cater to niches and many are already desperately trying to earn money from the web. One player already moving in this direction is Hachette Filipacchi Media. In June 2007, the company behind Car and Driver, Road & Track and Cycle World purchased Jumpstart Automotive Media, which sells advertising on Vehix, JD Power Autos and Shopping.com’s Automotive Channel.
