Being British offers ad agencies no competitive advantage in the U.S., Johnny Hornby told "Advertising Week Europe" this afternoon in a discussion on how to grow business abroad.

Sorrell told the Press Association: "Most of my wealth, if not all of it, is and has been for the last 31 years tied up in the success of WPP.

KLM is turning to chat bots to provide interaction that is intuitive and more natural to customers. "Business is moving away from company apps," Gert Wim ter Haar, social media hub manager at KLM, said at the DMWF conference in Amsterdam this week.
