Mark Robinson, the marketing director of J. Walter Thompson, is quitting the industry to join the Miracle Media Group, a media company specialising in film.
Robinson, who has worked at JWT for four years, will leave at the end of January.
He becomes managing director of Miracle Media, which owns a group of marketing services businesses including the Picture Production Company and the design agency North Creative.
While at JWT, Robinson was responsible for the internal and external marketing of the agency and has maintained a high profile in the advertising industry.
He was the chairman of NABS, the industry charity, for the past two years and is actively involved in the IPA, where he is a Fellow. He was also the founder of Radio Feltham, which is Britain's only prison radio station.
Before joining JWT, Robinson ran new business for Publicis, which he joined from Euro RSCG.
Robinson said: 'The role at Miracle provides an opportunity to be a part of a group of companies that can provide integrated communication solutions for a fragmented marketing world. It understands how to communicate the value of entertainment, and this can be taken to a broader audience.'
