Vinton, a former executive creative director of digital at Ogilvy & Mather, is leaving to work with other agencies in developing new television formats, although he may collaborate with Burnett in future projects. He has also been negotiating a film deal in Los Angeles on behalf of advertising agencies, involving product placement.
"I've been looking at brands in movies," Vinton said. "Previous attempts have been clumsy and looked like just product placement. This is about writing and co-developing scripts for brands."
Chris Harrison, the former managing director of Grey Interactive TV and co-founder of Spring, is now in sole charge of the company.
Bruce Haines, the group chief executive of Burnett, said: "We're sorry to see Marcus leave but are hoping we will have the opportunity to work with him again in the future in his new film role."
