A term for high school students in the 60's that were nerds/geeks. True audio visuals spent their time playing ping-pong on the computer and were usually members of the chess, math, and science clubs. AV's got their name because of their extensive knowledge in electronics (audio visual) which was uncommon in the 60's. These pioneers grew up to become the leaders in today's computer/science industry.
