LONDON: The major advertising agency holding groups will either have to further consolidate, or else sell off some of their prized assets, if they are to survive the economic and advertising slowdown, according to WARC Online's columnist, Tummler.

While companies like WPP, Omnicom and Interpublic have become one of the defining features of the modern advertising landscape, Tummler suggests the current agency holding group model must adapt if it is to survive.

Moreover, it is further argued that many agency networks may actually "blossom" if they were fully freed from "their holding company shackles and obeisance to Wall Street's corrosive ethos."
