IT Security: Defense against the digital dark arts

Google is a company founded on 4 September 1998 in the Google garage in Silicon Valley, California, by Larry Page and Sergueï Brin, creators of the Google search engine.

The company made its name primarily through the monopolistic position of its search engine, which faced competition first from AltaVista and then from Yahoo! and Bing. It has since made a number of acquisitions and developments, and today owns a number of noteworthy software products and websites, including YouTube, the Android operating system for mobile phones, and other services such as Google Earth, Google Maps and Google Play.
