Which came first, Android or the World Wide Web?

the World Wide Web came first, by 19 years. Tim Berners-Lee wrote the proposal at CERN.

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.

the World Wide Web

Berners-Lee circulated his proposal in March 1989, built the first browser and server by the end of 1990, and CERN put the software into the public domain in 1993. The Web is twenty years younger than the internet: the internet is the network, the Web is one service running on it, and email and file transfer both predate the Web by decades. The first website went live in December 1990 and is still online.
