Griffiths, who takes on the role of vice-president of marketing communications, has been with Sony for nearly 11 years, most recently as vice-president for the portable audio business group.
His role will cover more than 30 markets, including Russia and Central Europe, and he takes charge of all brand and through-the-line communications for Sony's consumer electronics and business products.
Sony said it plans to continue with the "you make it a Sony" strategy, created by Fallon. The agency was appointed in November 2002 by Griffith's predecessor Barbara Haase, director of marketing communications for Sony Europe, who has since left the company.
Griffiths said building relationships with customers was vital to building the brand. He said Sony was not just about products.
"The brand offers much more than that -- with pictures, movies and games to consider -- we are truly about fun and entertainment.
"I see part of my role as re-invigorating these values and reinforcing it not just in advertising commercials but right at the shop front as well. When you buy into Sony, you should be buying into a whole brand experience," he said.
