Interbrand, a division of Omnicom, is a brand consultancy, specializing in areas such as brand strategy, brand analytics, brand valuation, corporate design, digital brand management, packaging design and naming. Interbrand has 29 offices in 22 countries. Interbrand was founded by John Murphy, a native of Essex in the United Kingdom. His interest in branding design began while working in the corporate planning and marketing department at Dunlop Corporation, a leader in the tire industry. In 1974, Murphy left Dunlop and along with his wife opened Novamark, a product-naming consultancy. In 1979, Novamark opened an office in New York, under the name Interbrand, reflecting a shift in the companys offerings. No longer focused on naming and registering trademarks alone, the company was now involved in the more encompassing activity of brand strategy and design.
