Doodle marks Google's 13th birthday

What better way for search giant Google to mark its 13th birthday than with one of its own Google Doodles? Visitors to Google's website on Tuesday saw a birthday cake with one of Google's earliest logos. Some of the letters in "Google" wore a party hat and were "seated" at a table with a birthday cake and gifts and balloons. Clicking on the doodle will take a visitor to a search results page, with - what else? - Google as the top result. Google has had a tradition of doodles for its "birthday." Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in California. Page and Brin originally nicknamed their new search engine "BackRub." Eventually, they changed the name to Google, originating from a misspelling of the word "googol." the number one followed by 100 zeros. In May 2011, unique visitors of Google surpassed one billion mark for the first time, an 8.4 percent increase from a year ago with 931 million unique visitors. — RSJ, GMA News
