Well, we have our own physics laboratory (Fermilab) outside of Chicago with over 1,750 employees and $545 million in funding.
In 1989 an English scientist (Tim Berners-Lee) at CERN was working on how to allow scientists from around the world to access all the data CERN was spewing out. He invented the World Wide Web (WWW) commonly known as the Web.
