Which came first, Android or Wikipedia?

Wikipedia came first, by 7 years. Wikipedia launched as a side project to feed a different encyclopedia.

Side by side

Android

Android as a company was founded in October 2003 — four years before the iPhone — originally to build an operating system for digital cameras. Google bought it in 2005 and the first Android phone shipped in October 2008, fifteen months after the iPhone went on sale. So Android is older than the iPhone as a project and younger as a product, which is why the question needs the distinction stated.

Wikipedia

Wikipedia launched in January 2001 as a scratchpad for Nupedia, a peer-reviewed encyclopedia project started in 2000 that had produced about two dozen articles in a year. The wiki produced more than that in its first month and Nupedia was abandoned in 2003. Wikipedia is older than Facebook, YouTube, Twitter and the iPhone.
