Who Made the Internet

An attempt for a complete and orderly archive – by Mark Nichols

For thirty years the world has been taught a story about the Internet’s origin: UCLA, SRI, and BBN sent the first packets. CERN invented the Web. AOL mailed out a billion CD-ROMs and said, “You’ve got mail!”

And then The Magic Internet Fairy was bundled together with cable TV and the world was forever changed.

That story is not entirely wrong, but it is incomplete. The missing chapters have hundreds of real people and their names attached to them. The list below celebrates the individuals whose measurable and extraordinary contributions made the Internet what it is today.
