Microsoft has named Satya Nadella, head of its cloud computing business, as the company's next CEO. He immediately replaces Steve Ballmer, who had announced in August 2013 that he would retire from the world's biggest software company after more than 13 years at its helm.
Here's a look at key moments in Microsoft's history.

- March 26, 2004: At a conference for online advertisers, Ballmer says Microsoft's biggest mistake was failing to develop its own search engine, which caused it to fall behind rivals Google and Yahoo. "That's probably the thing I feel worst about over the last few years," says Ballmer. Ballmer vows to put more money into research and development of search technology at Microsoft.
- May 4, 2006: Ballmer says MSN Search, Microsoft's search engine, is gaining steam against rivals, but still trails Google and Yahoo.

- April 10, 2013: Research firm IDC says PC shipments fell 14 percent in the first three months of the year, the deepest quarterly drop since the firm starting tracking the industry in 1994. IDC blames Windows 8 for accelerating the sales decline by confusing too many people who had become accustomed to using the old operating system.
