How does electromagnetic radiation carry information? 

I've always been interested in how we can send information using electromagnetic radiation. Particularly how we can send both analog and digital information. I've tried doing some research but the explanations have always been far too complex for me. 

Edit: I had a simple understanding of digital transmission already and it seems to really be as simple as I thought. The reason why I had trouble was because of analogue transmission.

Take two loops of wire and connect them with another wire so they look like this O---O. Put a compass in one loop, and take a magnet and move it back and forth through the other loop. You should see the compass needle move slightly.

You have just made a working telegraph.
