In order to manage AMP as a commercial product, Uzelac partnered with American media entrepreneur Brian Litman to form Advanced Multimedia Products "AMP". Advanced Multimedia Products was later merged into PlayMedia Systems - also co-founded by Uzelac. AMP was more widely marketed beginning in 1998 and facilitated world-wide MP3 popularization.
