Former WPP CEO Martin Sorrell should have done more to promote creative inspiration during his reign over the advertising industry, a top executive told CNBC Monday.
Speaking on the sidelines of Cannes Lion festival, Ami Hasan, chairman at Art Directors Club of Europe (ADCE), told CNBC that Sorrell and other global leaders of the advertising industry had missed an opportunity to promote creativity over the last decade.
"The era of Martin Sorrell dominating the business … has not been that glorious because he mostly talks to investors and he mostly talks about money and his stock price and what the industry needs is a couple of figureheads that would speak about creativity," Hasan said.
"For us, for those that do the ads, it is extremely inspiring to hear these titans speak about creativity and unfortunately Martin Sorrell hardly ever does that," he added.
Martin Sorrell was not immediately available to comment when contacted by CNBC.
