This is just a list of some of the websites we will look at.
Google
One of the most popular search engines. This site also offers many additional features, such as maps and the "Google Docs" services.
Yahoo
Another popular search engine. It was originally just a list of websites written up by a couple of college students from Standford, but it was commercialized and taken over the investment capital. The current version is almost unrecognizeable compared to the original. Yahoo is playing a game of catch-up with Google. Large portions of Google are owned by AT&T.
Wikipedia
Amazingly good online encyclopedia
Facebook
Online social network site.
