Happy birthday, Google. You didn't invent Android, but you made it awesome, for which we are sincerely grateful. Most of the other stuff that you do is pretty cool too. We'd tell you to watch a certain John Hughes movie, but you're too young to appreciate the reference.

Google declared September 27th its "official" birthday with a 15-year celebration last year, though a precise date for the start of the company isn't really known - you could say that the start of the project goes back at least 18 years to when Larry Page and Sergey Brin began work on their custom "BackRub" search engine at Stanford University. The company was officially incorporated on September 4th, 1998, though an earlier version of Google was posted on Stanford servers before then.

Android's official birthday is November 5th. This commemorates the day that Google introduced the Open Handset Alliance in 2007, though the original "Android" company was started by Danger Inc. co-founder Andy Rubin and others way back in 2003 and acquired by Google two years later.
