NEW YORK (TheStreet) - Digital advertising is on the rise and is something investors should be paying attention to. At least, that's what Martin Sorrell, CEO of WPP PLC (WPPGY) , told TheStreet's Ruben Ramirez.
WPP, the U.K. based communications services company, reported slightly lower-than-expected revenues in the third quarter.
"Things have tightened up" a bit, Sorrell reasoned, as geopolitical issues -- like Ebola, terrorism in the Middle East, and demonstrations in Hong Kong -- have caused investors to become uncertain.
"Our clients don't like uncertainty," Sorrell said. But thankfully, many of the current issues from around the world seem to be dissipating to some degree. At least, it seems that way with Russia and Ukraine reaching an energy deal and Japan's increased stimulus program, with the two events helping to ease global concerns.
Geographically speaking, he said the fastest growing region for the company is the U.K., followed by many of the emerging markets, like Asia, Africa and Latin America.
These regions are "still dominated by the growth of digital," he explained, with the "most potent force" being mobile ads and mobile search.
