Dusk is the darkest stage of twilight in the evening. Pre-dusk, during early to intermediate stages of twilight, there may be enough light in the sky under clear-sky conditions to read outdoors without artificial illumination, but at the end of civil twilight, when the earth rotates to a point at which the center of the sun is at 6° below the local horizon, artificial illumination is required to read outside.

Dusk! is a premium monthly subscription television channel. Established in 2009, Dusk! is the first and only adult TV channel in the world aimed at a female audience. Demand for female-oriented adult films, porna or women's erotica has been increasing for many years and is becoming increasingly accepted. Dusk! believes women have their own fantasies and needs and therefore require a different kind of adult films. By questioning its female users via an online panel, Dusk! has become an expert in this area. Dusk! is available in The Netherlands on the platforms of Ziggo, UPC Netherlands, CAIW and KPN and broadcasts 24/7. The channel is owned by 2GrapesMedia.
