Advertising conglomerate WPP is looking to increase its Web advertising revenues through more acquisitions. Last year it purchased 24/7 Real Media for $649 million, and is currently making a run at Nurun, a Montreal-based interactive ad firm. But it may try to boost its Advertising 2.0 cred even further with more small acquisitions.

The NY Post, not always the most reliable source but pretty good when it comes to Madison Avenue, reports that possible acquisition targets include Spot Runner (cheap TV ads for local businesses), VideoEgg (video ads and a Facebook play), or JumpTap (mobile ads). WPP is already a minority investor in both Spot Runner and VideoEgg. Quick, sell those ad startups before the recession hits.
