Which came first, Google or Harry Potter?

Harry Potter came first, by one year. Harry Potter and the Philosopher's Stone was published in the UK.

Side by side

Google

The date used here is the incorporation, 4 September 1998. Two others compete: the research project called BackRub began at Stanford in 1996, and the google.com domain was registered on 15 September 1997. Google itself has celebrated its birthday on four different September dates over the years, which is a fair indication that no single one is correct. It is younger than Amazon, eBay and Netflix.

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.
