Google AdWords goes AdPics + AdMovies ?

Why should Google stay only with words for advertisments? - It may be right, that not everywhere pictures and movies are welcome (e.g.: the Google homepage).

But what about Flickr, Picasaweb, YouTube? If the eye is focused on one type of information (e.g.: pictures) and the bandwidth needed is already within the same order of magnitude, why not use pictures and movies?

Many products cannot be advertised well only with words, just open your mind!
