Google crawls and indexes many web pages, increasing the liklihood of returning what you are searching for. Google is pretty good at populating your search field with what you are already looking for.
If you go to Google’s home page, there is a little celebration piñata Doodle to play. Simple, fun, and doesn’t stray you too far away from what you were originally doing.
Google’s AccomplishmentsHere is a great website showing the 15 years of Google and all its accomplishments. http://www.google.com/about/company/timeline/
The timeline goes all the way back to when Google’s name started out as “googol”.
Google has a slew of accomplishments, and I’m sure many more to come. So Happy Birthday Google, you have a lot to celebrate about!
