Tim Berners-Lee submits a proposal (12-3-1989)

"Information and management: a proposal", submitted to CERN, to address the question "...how will we ever keep track of such a large project?"
The proposal uses the image of "a 'web' of notes with links (like references) between them...like a diagram of circles and arrows, where circles and arrows can stand for anything'.
Later that year, TB-L "implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet." (Wiki)
And that, children, is how it all began....
