WPP Group, a mega-ad agency conglomerate is merging with (read: buying) Grey Global for $1.5 billion.
My contention: Any ad agency this big can't do great marketing for its clients and still make money. Being this big, there will be an even bigger bias towards a brute force approach to marketing, because mega-media commissions are necessary for survival.
Corollary: The only way they can make money is if enough clients buy bad advice from them.
Debate me on this one!
