Producing oral can be done by the body. Producing print or video requires external tools. So oral is more built-in than video. Visual things like body language are more built-in than oral.

The word "litteracy" is so linked in to the printed word that it would be hard to debate the questions posed by harold.

Hmm.. litteracy is a bad word. Litt !
