LONDON – WPP is eying investments and acquisitions around technology platforms which power media buying, says CEO Sir Martin Sorrell in this interview with Beet.TV.  He says we are now “math men not Mad Men,” a reference to the popular television show about advertising.

In this extended conversation taped at the FT Digital Media Conference, Sir Martin addresses global video consumption trends, the growth of digital revenue  at WPP, and the role of Google, Twitter and Facebook in the media landscape.

At the conclusion of the conversation, he cautions the industry not to be complacent by a buoyant media business with high stock prices.
