Just weeks after the research and strategy outfit was acquired by Mark Penn’s Stagwell Group from Nielsen, National Research Group (NRG) has named Jon Penn as its new CEO. Penn will replace Howard Ballon, the former NRG exec appointed Interim CEO after the company was sold to Stagwell: Ballon will remain with NRG as Executive Vice President once the transition is complete.

Penn joins NRG following nearly two decades at market research consulting firm Penn Schoen Berland, founded in 1975 by Mark Penn and Douglas Schoen, where he headed up the company’s Media and Entertainment Practice and most recently held the position of Global Chief Executive Officer. In his new role at NRG Penn will work to strengthen the company’s ties to the entertainment industry, with an emphasis on modernizing existing offerings, expanding into the digital space, and expanding NRG’s global reach.

NRG is one of the largest companies providing film studios with market research about their releases, and currently employes more than 100 employees people between its Los Angeles and London offices. The company is the second marketing services acquisition by Stagwell in 2015, following the purchase of SKDKnickerbocker LLC in October.
