Audio Visual

The Term audio-visual (AV) may refer to works with both a sound and a visual component, the production or use of such works, or the equipment involved in presenting such works. 

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 using sorftware such as PowerPoint.  Audio-visual is used usually as industry jargon, expressing works with a type of visual and/or audio format.  Most work today with AV is in the industry of movies, and usually now deals with digital technology.
