Since 1992, Satya Nadella has brought Microsoft engineering expertise, business savvy, innovation and the ability to bring colleagues together, says Microsoft founder Bill Gates.

Yesterday was a historic day for Microsoft with Satya Nadella’s appointment as the company’s new CEO.

After a six-month long search following former CEO Steve Ballmer’s retirement announcement, the corporate board appointed frontrunner Nadella CEO over other candidates that included Microsoft executive vice president Tony Bates and Ford CEO Alan Mullaly.

A Microsoft leader for 22 years, Nadella has inspired tech and news analysts to predict that he will usher in a new era for mobile at Microsoft, which has long been stalled during Ballmer’s tenure. This has the potential to push the Gates-founded enterprise to its former legacy of groundbreaking innovation.
