Microsoft vs. Google: The Digital Future

First there was Microsoft, and a colossus made from software for the personal computer. Then those PCs got tied together on the web, and there was Yahoo, a giant hub for e-mail and chat rooms and all the web brought.

Then there was Google, the uber search engine and high-minded master of the Internet universe, with a mountain of web advertising and a vision of Microsoft going the way of the Model T.

Now it's war. Microsoft is trying to gobble up Yahoo for $44 billion dollars and take on Google.
