Microsoft came way before Facebook and the technology is obviously both complex and valuable. The two platforms are quite different, like comparing apples to oranges.

Facebook consists of a database that holds user profiles and a front end for viewing and editing them. You can build a Facebook-clone in a week.

Microsoft has hundreds of products, some of which took decades to develop. Windows XP alone has over 40 million lines of code.
