Google turns 10: A look back

Google goes after Microsoft on multiple fronts. The search giant completes its $3.1 billion acquisition of ad server DoubleClick, a company that Microsoft CEO Steve Ballmer (right) wanted. Google also strikes a search partnership with Yahoo, which Microsoft also wanted. In September, Google, its shares down 40% from their all-time high in 2007, takes on Microsoft's Internet Explorer with its own Web browser, Chrome. Google also prepares to launch its Android mobile operating system to compete with the Apple iPhone and Microsoft's Mobile OS.
