Santa Monica-based Activision reported Friday that it had an estimated sell through of more than $400M on its new title, Call of Duty: Modern Warfare 3, in the first 24 hours of its release. The firm said it sold more than 6.5 million units in North America and the United Kingdom alone with the release. The sales figures surpassed last year's release of Call of Duty: Black Ops, which had $360M in first day sell-through, and Call of Duty: Modern Warfare 2, released in 2009, which had estimated first day sell through of $310M.
