Levick, who will take the title of president, global advertising and strategy, officially joins AOL in May and will be responsible for the company's worldwide advertising business, developing global revenue strategies. He will report to AOL chairman and chief executive Tim Armstrong.
Amstrong and Levick worked together at Google for more than seven years. Coleman, the former executive vice-president of global sales at Yahoo, and digital veteran, only joined AOL as president of Platform-A in early February. He will now leave the company.
At Google, Levick was responsible for business marketing activities for the Americas, as well as sales development and strategy for all of the vertical industries covered by Google's Americas sales organisation.
Levick joined Google in 2001 and has held various executive management positions in the company's advertising sales organization in both North America and Europe.
Last month, Armstrong joined AOL from Google, where he held the position of president of North American sales.
Yesterday, AOL reported its global ad revenue fell by a fifth year on year in the first quarter of 2009, sparking further speculation that the business will soon be spun off by parent company Time Warner
