Over the last few years, we have observed as the big ad agencies have found a growing percentage of their revenue made up by two growth factors – digital and emerging global markets.

Now WPP’s CEO Sir Martin Sorrell, becoming the latest LinkedIn influencers writer, is setting his target higher still: “Now we will accelerate the implementation of our strategy by raising our targets from 35-40% for both fast-growth markets and new media to at least 40-45% each over the next five years.”

In fact, Sorrell told Beet.TV of that ambition in this fascinating video interview back in April (republished here), when he also said: “Digital is 34%. It moves at least by one percent a year [organically].

“You have to be paranoid, you have to be willing to make changes, to push your people to move faster and you have to be willing to experiment – and, if necessary, fail.”
