Chomsky Normal Form - what is it?

Here we give a complete and correct proof of Chomsky Normal Form, which is a restricted form of context-free grammars, and the proof is that every CFG can be converted into CNF. Many proofs out there give a "hand-wavy" argument, but we give a technically sound argument at each step of the way. There are 5 stages - watch the video to find out what the 5 are!
