Rock Dünyasi (rock world), with the subtitle "rock kültürü dergisi" (rock culture magazine), was founded in 1991 when there were no other music magazines on the Turkish market but Boom Müzik Dergisi and Blue Jean. The idea was to publish it monthly, but only 15 issues could be printed in the next 3 years. (Yoldan Çıkmış Simalar)
