Which came first, Google or YouTube?

Google came first, by 7 years. Google Inc. was incorporated in a garage in Menlo Park.

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.

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.
