Animation is a series of still drawings that, when viewed in rapid succession, gives the impression of a moving picture.There are many reasons to pick animation as a medium to promote your business: You can use animation to draw attention to something you want the user to look at. This can range from blinking text to movement of items as in a cartoon. It is primarily used in online advertisement. Another reason to have animation is to help to demonstrate something you are explaining in your message. Although a picture or illustration is useful, in some situations it is not sufficient to describe some action. An animation or video is necessary.
