 Visuals in one form or another have always been a part of live DJ performances, but until the advent of this form of performance, the visual aspect was largely limited to computerized strobes and spotlights, laser projectors, and/or pyrotechnics.With the advent of DVD technology (especially once it became cheap enough for the average individual to create his or her own discs), a push was made for a device that would give a performer the same flexibility in accessing the music and video on the disc as the turntable-style CD players commonly available for DJs.Pioneer Corporation became the first (and as of this writing, still the only) manufacturer of DJ equipment to produce such a device, the Pioneer DVJ-X1, first released in 2004.
