Bob Pittman is advising Al Gore on buying a cable network, has bought Daily Candy and reportedly plans to develop the online newsletter in multiple media (cable anyone?) and is now joining forces with Strauss Zelnick, the newest direct marketing maven, to buy OTX, a market research group owned by ifilm whose online test platform allows testing of interactive media. The blurbs tout OTX’s ad capabilities, but I bet, once Pittman owns it, he will test content as well as advertising (uh, duh).
