The term Audio-Visual (AV, or A/V) may refer to works with both a sound and a visual component, the production or use of such works, or the equipment used to create and present such works. Slide tape presentations,^[1] films and television program are examples of audio-visual presentations.^[2]

Once audio-visual media came into existence, it became a part of people's everyday lives within a few decades.^[3]

Business presentations are also usually audio-visual. In a typical presentation, the presenter provides the audio by speaking, and supplements it with a series of images projected onto a screen, either from a slide projector, or from a computer connected to a projector using a presentation program (software).

In the developed world, there has been a huge uptake of computer-based audio-visual equipment in the education sector, with many schools and higher educational establishments installing projection equipment and often using interactive whiteboard technology.
