The 25 Most Influential People at Microsoft - 18. Pieter Knook
18. Pieter Knook, Senior Vice President, Mobile Communications Business Microsoft's Windows Mobile business has hugely grown under Knook's leadership. Mobile is a strategic business that will grow in importance, particularly as more handsets are used for data as well as voice. Microsoft is heavily investing in mobile technologies, particularly as it looks to future advertising revenue possibilities. Knook's star also is rising.
Among Microsoft's 70,000-plus employees, there are many influential people. Twenty-five is too small a number to capture the best of the best among a large group of creative people. But Microsoft corporate culture also is very staid and insular, with a top-heavy power structure. Therefore, for this list, I focused more on operational influencers, although there are some thought leaders included. By Joe Wilcox, Microsoft Watch
