Dupree was previously at Arbitron, where she spent 19 years and was executive vice president responsible for the development of new multimedia products. She was also co-general manager of the Project Apollo joint venture with Nielsen, which was ultimately abandoned last year.

She left the radio ratings firm in April as part of CEO Michael Skarzynski’s “staff realignment” project.

In her new role, Dupree will be responsible for “directing Innerscope’s continued growth and positioning at the forefront of next-generation media and marketing research”, the company said in a statement.

Innerscope CEO and co-founder Carl Marci said: “Linda’s deep insight and understanding of the revolutionary technologies that are advancing media research, as well as her experience with those companies that comprise our core business, will continue to drive Innerscope’s growth. We’re thrilled to add someone with such broad and deep expertise.”
