In-game ad agency Double Fusion has appointed four new executive staff members, including Channing Chor, formerly of Fox Interactive Media, and former IGN Entertainment executive Jennifer McLean. The announcement of the new members of the company's management team follows its hiring of former EA executive Julie Shumaker as vice president of worldwide sales. Chor will take on the role of business development manager at Double Fusion, while McLean's new role is that of Double Fusion's senior director of marketing. Other new additions include attorney Alex Sood, who joined as the company's senior director of legal affairs and operations, and Nir Hasson, who has come on board as the firm's senior programmer. Chor will be a manager within Double Fusion's content acquisition group, which develops partnerships with game publishers. McLean comes to Double Fusion to head up the company's communications efforts from IGN Entertainment, where she served as director of marketing. Sood will serve as legal counsel and head of business operations, including the company's expansion into Asia. Finally, in his role as the senior programmer, Hasson will lend his expertise involving computer graphics and image processing, 3D real-time graphics engines and computer games to Double Fusion's client SDK team. "Alex, Jennifer, Channing and Nir each bring an excellent reputation and incredibly honed skill set to their positions at Double Fusion," said Jonathan Epstein, president and CEO. "All of our clients and partners, from advertisers and agencies to developers and publishers, will benefit from the level of quality service Double Fusion is able to deliver through our ever-expanding team of industry professionals."
