What type of web development tutorials do you prefer?

I’ve been giving a lot of though to the tutorials I create recently, when I go through tutorial sites I prefer video tutorials which got me thinking what type of tutorials do you prefer, written or video. 

To that end I have a small poll please vote on your preference.

Thanks to everyone who votes, at first I though video would be way ahead of written content but it turns out I was wrong about that, looking at the results its clear written content is wanted as is video content.
