“As the world around us changes, NPD will keep evolving and innovating to help brands and retailers address new challenges and opportunities,” Schoenbart said in a release Monday afternoon.

She replaces Tod Johnson, chairman and chief executive of NPD since 1971. Johnson will be the company’s full-time executive chairman and work with Schoenbart on strategy. He will also “focus on long-term planning, research and special initiatives,” the release said.

Schoenbart will continue to oversee the global operations and execution of the business.

“This promotion, to a large extent, reflects how we are operating,” Johnson said in a statement.
