the World Wide Web came first, by 16 years. Tim Berners-Lee wrote the proposal at CERN.

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.

YouTube

The youtube.com domain was registered on Valentine's Day 2005, the first video — "Me at the zoo", 19 seconds of a co-founder at San Diego Zoo — was uploaded on 23 April, and the site opened publicly in the winter. Google bought it in November 2006 for $1.65 billion, about twenty months after the domain was registered. It is younger than Facebook by a year and older than Twitter by one.
