The purveyor of burgers to the planet, McDonald's, has announced the appointment of former Quaker Foods president Mary Dillon to its chief marketing role.

Dillon, who joins the fast food giant next month, replaces retiring Larry Light. She will be responsible for global brand management and report to president/coo Mike Roberts.

Gushes the new cmo: "This is one of the best marketing jobs in the world, and I am excited and immensely proud to join this world-class team that touches millions of consumers every day."

Light, who hangs up his spatula at the end of the year, has been in the post only since 2002 and spearheaded the company's first global marketing effort, the love-it-or-loathe-it I'm lovin' it campaign.

McDonald's roster of advertising agencies includes Omnicom's DDB Worldwide and TBWA Worldwide, and Publicis Groupe's Leo Burnett. The company spends an estimated $1.3 billion (€1.05bn; £721m) annually on global advertising, about half of which is dedicated to the US.
