Dialogue in the Dark ("Dialog in the Dark" in American promotional materials) is an awareness raising exhibition. It is a social franchising company, offering exhibitions and business training in total darkness, creating jobs for the blind, disabled and disadvantaged worldwide. In Dialogue in the Dark blind guides lead visitors in small groups through different settings in absolute darkness. The visitors learn how to interact without sight by using their other senses. The exhibition offers the public an experience that can change mindsets on disability and diversity, and increase tolerance. Since its first opening in 1988 over six million visitors from more than 25 countries have experienced Dialogue in the Dark, giving over 6,000 blind people jobs.
