Many works have been written on the subject of TV and its immediate problems, but consideration of the power and effects of television is rare. Television is highly effective, no matter what its content may be. Consequently, it would be wise for us to appreciate the brute power of it and the special danger that it poses to children. Its power springs in large part from the fact that it combines the wonders of sight and sound. The sound has recognizable imprinting power.
Visual images have similar effects on young children.
I still remember every page of my favorite picture books from my childhood, even though they lacked animation. It is therefore understandable that the combination of audio and fully animated video results in a permanent engraving of images and ideas upon the mind. When you hear a radio drama, for example, pictures of what is going on in the story come into your mind. They are the products of an active imagination. Similarly, when a child looks through a picture book, the story can be derived with a little effort.
