Summary: NEW YORK (AdAge.com) -- WPP Group CEO Martin Sorrell not only thinks the contraction of the newspaper and magazine industry will continue, but that it NEEDS to continue. In keynote remarks that opened this week's Ad-Tech in New York, Sorrell cited the over-capacity of supply and inventory as a major problem holding back the re-stabilization of the media business. He also predicted that ad agencies would be getting "very much more involved" in the development of content and that the lines between advertising and editorial are going to get "much more blurred" than they already are today.
