  They've had videos for about as long as they've existed. OP is misinformed.

    Available material vary considerably between courses, and those with video lectures are in minority.

    There was very little video and audio when it was started. Remember it dates to 2002 (i.e. three years before YouTube was founded) and it wasn't really routine, easy, or inexpensive to take video of lectures, edit it, and host it online. Also, as I said in another comment, the main impetus of OCW was to provide materials for educators to use in order to create their own courses. In a way, I suppose it was part of a similar top-down, enable institutions to provide local learning opportunities thinking that One Laptop Per Child was part of as well.
