GSD&M

GSD&M is an advertising agency headquartered in Austin, Texas, United States. It was founded in 1971 by graduates of University of Texas at Austin – Roy Spence, Judy Trabulsi, Tim McClure and Steve Gurasich, and others, as AdVantage Associates. After the 1972 political campaign for former Texas Senator Ralph Yarborough, it re-organized with the 4 principals, as GSD&M. Since 1998, GSD&M has been part of the Omnicom Group. A satellite office is located in Chicago, Illinois.

Recently the agency was awarded the business for Chipotle and Hampton Inn and Suites.

The agency started with local retail accounts and expanded to more regional work. In 1986, the agency created the Don't Mess with Texas anti-litter slogan for the Texas Department of Transportation.

In the 1990s GSD&M began to acquire more national brands outside of Texas and was regarded as a "creative hot-shop." The agency relinquished Chili's, DreamWorks, Frito-Lay, Fannie Mae and UnitedHealthcare in 2006–2007. The agency's Omnicom sibling, BBDO, was given the lead on the AT&T account, although GSD&M still has a portion of the business.
