AT&T announced it has selected Austin-based GSD&M’s Idea City to handle advertising and marketing duties for AT&T 411 and 1-800-YellowPages. GSD&M says that with this deal, it now handles all creative duties for AT&T’s directory and search services, as well as its consumer direct TV business.

The agency said it will develop a new marketing strategy while retaining the “Your World, Delivered” tagline.

“Consumers have many choices to find information,” said Wendy Clark, senior vice president of advertising at AT&T, in a statement. “With AT&T, you get local, relevant and reliable information anytime, anywhere and in whatever way you want it. There’s no better partner to help spread that message than GSD&M Idea City.”

Idea City developed the successful Yellowpages.com “Need Something?” campaign as well as handling the rollover of SBC Yellow Pages to AT&T Real Yellow Pages that increased usage numbers across the United States.

“We’ve had a long, successful relationship with AT&T,” said Duff Stewart, president and chief operating officer of GSD&M. “We are honored that AT&T selected us to help drive the marketing efforts that will position AT&T as the premier choice for local search information.”
