## The man who turned paper into pixels

"It was the change that no-one saw coming: the idea that we could take a book, a painting or a song and send it through cables and wires and even thin air to the other end of the world - and it would be identical on the other side. But this idea underpins everything about the Information Age we live in.

How did we make such a mind bending transition into the digital world? And how does it work? It turns out it's all based on a concept that is surprisingly beautiful in its simplicity. This short video essay explores what that idea is and tells you about the man who figured it all out."
