Speech was originally used to exchange information, then people began telling stories through drawings and cave paintings. The development of written language provided another medium for expressing thoughts. Now, people commonly use various media like speech, sounds, music, text, graphics, animation and video. Multimedia involves combining two or more of these elements of text, graphics, audio and video. It has expanded the potential uses of media and made the internet a more engaging place. Multimedia is now widely used for advertising, entertainment, education and sharing public information.
