As the glamor and glitz of 2019’s TV upfronts season transitions into the nitty gritty making of that ad sausage, the world’s largest buying organization has named new leaders in its most important market.

Today WPP media network GroupM rounded out its U.S. C-suite with three promotions and one hire as North American CEO Tim Castree continued his plan to streamline the business after taking over for Brian Lesser, who now runs AT&T’s ad platform Xandr.

“What we are doing is really about … simplifying the complexity brought on by media fragmentation and supporting clients with the best digital data performance available.”
