Walter De Brouwer set up Riverland Publications with the help of Bill Ziff in 1990 to publish personal computer magazines in the Benelux. In 1994, when Ziff announced the sale of the publishing empire to Forstmann Little & Company, De Brouwer sold his titles (Computer Magazine and CM Corporate) to VNU.
He continued publishing WAVE, the 'techno-anarchist' gigazine. Wave was thecult Belgian avantgarde magazine, joining Boing-Boing as bridge between the underground and the world of the future. Wave shared writers with the San-Francisco-based Mondo 2000,such as R.U. Sirius, William Gibson and Douglas Copland. Unable to stop the advance of Wired, both 8-colour magazines went into cyberpunk history. The covers of the magazine, edited by Michel Bauwens and designed by graffiti legend Niels Shoe Meulman, were put on display in the San Francisco Museum of Modern Art.
