Google Analytics was originally developed from the Urchin on Demand software that Google acquired in the spring of 2005 (Urchin is still developed and available through value-added resellers, and is currently at version 7). The first Google-branded version was released in November 2005.
In 2006, further ideas from Measure Map (developed by Adaptive Path) were integrated into analytics when Google acquired them.
Early on, analytics was available by invitation only, as demand for the product was very high. It wasn’t fully available to all users until nearly a year after its initial release (August 2006).

It gives you an enormous amount of information about who is visiting your site, what they are looking for, and how they are getting to your site. Any business that wants to expand and grow their business on the internet should definitely be using Google Analytics.
