When it comes to video, there is no one more powerful in the porn world than Thylmann, who is managing partner of Manwin Group. He is simultaneously feared, hated and admired by many within the industry. Notoriously press- and camera-shy, he controls the Brazzers and Reality Kings collection of websites as well as several adult "tube" sites (think YouTube for porn), Digital Playground and Playboy TV. Manwin has been on a buying spree for years. His power position could be in jeopardy, though. In December, Thylmann was arrested on suspicion of evading taxes – and Die Welt reported German officials seized several computers and documents at Manwin's German offices.
