Interactive multimedia allows users to control, combine, and manipulate different types of media like text, sound, video, graphics, and animation. It is used for education, training, games, simulations, information and corporate presentations.

Videos and audio can be shared on sites like YouTube and SoundCloud, browser-based games do not require installation, online tests display automatic results, courseware simulates online classrooms, and podcasts and vodcasts are episodic series streamed online.
