Google have been around for some 10 years now and they have become a byword for an online search, a synonym with the speed and accessibility of the web.
That is not all they do of course, the list is massive.
Gmail – the nicest web based mail I have ever used
Analytics and Adsense – beautiful
Google Maps– perfect
Google Chrome – swift and understated yet brutally stable browser.
There is more, lots more, look at Google Options
