Reverse graffiti, also known as clean tagging, dust tagging, grime writing, clean graffiti, green graffiti or clean advertising, is a method of creating temporary or semi-permanent images on walls or other surfaces by removing dirt from a surface.

 The inspiration for the Videograf series came during the summer of 1988, from the graffiti zine movement.
 It was publications like New York City's "International Graffiti Times" published by David Schmidlapp and Phase2 and the first color graffiti zine from Los Angeles - "Can Control Magazine" published by Power that planted the idea of doing a videotape version of a fan zine.
 By February 1989 Videograf issue one was in full production.
 By the summer of 1989, photographer and graffiti artist William "Nic One" Green joined the Videograf team as a producer.
 A year later the future cofounder of Egotrip magazine, writer and television producer Sacha Jenkins joined Videograf as well.
 The Videograf Productions operation was run out of Henry Chalfant's studio at 64 Grand Street for about 3 years before moving to Greenpoint Brooklyn.
