Google celebrating its 13th birthday today. The search engine as usual posted a birthday doodle. "Google filed for incorporation on September 4, 1998, was established three days later on September 7, and the Google.com domain was registered September 15. All have been considered Google's "birthday" at one point, but Google has officially chosen September 27 as their day."
Doodles, the special logos have been around since Aug. 30, 1998. But, the first Google Doodle celebrating their birthday appeared on Sept. 27, 2002, on their fourth birthday, when Larry Page and Sergey Brin attended the Burning Man festival.
In other Google releated news, the search company today introduced "CityVille" to its social networking project Google+.
CityVille is Zynga's largest game on Facebook, with about 70 million users per month, according to AppData.
"It's no secret we're big fans of Google+ here at Zynga," Zynga wrote in a blog post. "…naturally we wanted to 'build' a presence for it on Google+. Ultimately, we want to make our games accessible to everyone, everywhere - no matter where they play or what platform they play on."
