Wall Street Journal: WPP CEO Martin Sorrell, who runs the world’s largest ad holding company, took the opportunity at a Cannes Lions panel discussion to defend traditional media. He said that videos on Facebook, where a “view” is counted after 3 seconds and users mostly watch with the sound off, isn’t equivalent to a TV ad. “Traditional media, linear TV, [and] newspapers in their old form are more effective from an engagement point of view,” Sorrell said.
