Which came first, Harry Potter or the World Wide Web?

the World Wide Web came first, by 8 years. Tim Berners-Lee wrote the proposal at CERN.

Side by side

Harry Potter

Bloomsbury published the first book in June 1997 with a print run of 500 copies, most of which went to libraries, after twelve other publishers had rejected the manuscript. The company's chairman gave the first chapter to his eight-year-old daughter, who demanded the rest. It came out the same year as Netflix was founded and a year before Google.

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.
