The CEO of the WPP Group said traditional media companies - including WPP's own ad agencies - are not reacting fast enough to the rapidly shifting digital media landscape, writes AdWeek. "I'd have to say our traditional verticals inside our business probably, like any traditional business, are slower than they should be in embracing new technology," said CEO Martin Sorrell at a client summit organized by WPP search agency Outrider.

The slow pace of change is partly the result of an older generation of leadership, the 61-year-old Sorrell said. For that reason, the top two priorities at WPP are reorienting to capitalize on fast-growth international markets and the explosion of digital media, he said.
