Ads giant WPP plans for life after Sorrell

Sorrell has headed the advertising giant for three decades.
The worldâs largest ad company is identifying internal and external chief executive officer candidates, the chairman, Roberto Quarta, said in the annual report on Friday.
Mr Sorrell, Britainâs highest-paid chief executive, is receiving compensation valued at ÂŁ70.4m (âŹ90.5m) for 2015, according to the report.
Most of the sum comes from a controversial incentive plan, which has triggered protests from shareholders and public interest groups.
While Mr Sorrell, 71, hasnât announced any plans to step down, it will be a challenge to find a leader who can bring similar visibility to WPP, as it seeks to outpace rivals, Publicis Groupe, Omnicom Group, and Havas.
Mr Sorrell is known for more than his marketing know-how, weekly appearing on television, and attending events such as the World Economic Forum, to comment on everything from economics to politics and fashion.
He popularised terms such as âbathtub-shapedâ to describe economic recoveries, and âgray swansâ to foreshadow trouble.
âHe has a legacy almost on the level of Steve Jobs, with what heâs done to the world of advertising, with Publicis and Havas having always followed,â said Cyrus Mewawalla, a media analyst at CM Research, in London.
âSorrell has brought traditional advertising into the digital age,â he said.
Mr Sorrell bought wire-shopping-basket-maker, Wire & Plastic Products, in 1985, and used it as a shell to build an advertising conglomerate, which today operates in 100 countries and boasts a valuation of ÂŁ21bn.
Although heâs led the company from the start, he has faced calls, from investors, in recent years, to outline succession plans.
âShareowners should have no doubt that we already have a strong pool of internal and external candidates to draw from,â Mr Quarta said in the annual report.
âI, and the other independent members of the board, will continue to focus on this in 2016, and beyond,â he said.
Under Mr Sorrellâs leadership, WPP acquired ad agencies, Ogilvy & Mather, Grey, and Young & Rubicam, and his companies have crafted campaigns such as the Dove âReal Beautyâ commercials.
Mr Mewawalla said WPPâs goal should be a successful succession, like the one undertaken at Microsoft, where Satya Nadella took over from Steve Ballmer, in 2014.
âNadella is in charge and everyone knows that and heâs gotten no overhang from Ballmer, or former CEO Bill Gates,â Mr Mewawalla said.
