Ms. Thompson, 57, who left Nissan North America unexpectedly as VP-marketing communications in September, has returned to Omnicom Group.
Tom Harrison, chairman-CEO of the holding company's Diversified Agency Services group, told Advertising Age that he created a new exec VP position, reporting to him, for Ms. Thompson. She'll consult on strategy for Chrysler and other auto accounts, although probably not Nissan, he said.
Mr. Harrison said he met Ms. Thompson about eight years ago, when she was brought in to run The Designory, a marketing services company within DAS. He said that while at Designory, she built up the Mercedes-Benz account and began developing a lot of digital communications.
"She's in and of the auto industry," he said of Ms. Thompson. "She knows it very well because she understands where the industry has been and where it's going."
Ms. Thompson, who did not return calls for comment, has extensive auto-industry experience. She started her auto career at Chrysler before joining Toyota in 1984 and moving to Mazda in 1989. She was honored in 1992 in Advertising Age's annual Marketing 100, when she was VP-marketing at Mazda, for the Miata launch, and again in 1995 as VP-general manager of the U.S. golf division of Wilson Sporting Goods Co. for rejuvenating the brand.
Ms. Thompson was also named a "Power Player" by Advertising Age in both 2005 and 2006 for her work at Nissan, which she joined in 2004 after five years as CEO of Designory.
