Greg Stuart will give up the CEO’s post at the Interactive Advertising Bureau at the end of this year, kicking off a search for a successor.
The IAB said Mr. Stuart was looking to pursue “new opportunities.” Recruitment specialist Spencer Stuart is heading the search.
Mr. Stuart most recently co-authored with market researcher Rex Briggs an advertising book called “What Sticks.” He joined the New York-based organization in 2001.
The IAB is the leading lobby for interactive marketing agencies and firms. It also produces guidelines and research, including a recent estimate predicting a 16 percent jump in interactive advertising this year to $16 billion.
