As we all know, books use text to convey ideas and quite often there are no images or illustrations to picture the scenes described in the book; therefore, we have to use our own imagination while reading. For example, reading a fantasy novel that contains mythical creatures one would normally see the appearance of those characters in their mind while following the plot. In contrast, movie heroes on a TV screen are usually created for the viewer by directors and producers of the film. Watching TV substitutes the need to develop one’s own imagination because the characters and their surroundings are shown on the screen.
