Two weeks ago, AFP informed us that "Google, at age 10, is the official heart of the Internet. Born 10 years ago, the Google Internet search engine has grown into the electronic center of human knowledge by indexing billions of web pages as well as images, books and videos." That's true, except that Google is 9 years old. Even if Larry Page and Sergey Brin registered the google.com domain in 1997, Google was officially launched one year later.
"Google opened its doors in September 1998. The exact date when we celebrate our birthday has moved around over the years, depending on when people feel like having cake," says Google's help center. You can read more about it directly from Google. In the recent years, Google's birthday has been celebrated on September 27th with a doodle displayed on the homepage. Happy birthday, Google!
Update: "Happy Birthday, Google!" is in Google Hot Trends.
Update 2: A reader noticed that Google used in this year's logo a piñata, "a brightly-coloured paper container filled with sweets and/or toys. It is generally suspended on a rope from a tree branch or ceiling and is used during celebrations".
