Tomislav Uzelac is the Croatian programmer who created AMP, considered the first successful MP3 player.[1]

Uzelac studied at the University of Zagreb's Faculty of Electrical Engineering and Computing (FER) under professor Mario Kovač, working on MP3 software decoding.[2] In 1997 he created AMP,[1][3] and also graduated with an engineer's degree from FER. Two students from the University of Utah, Justin Frankel and Dmitry Boldyrev adapted it to work on Windows and called it Winamp.

In order to manage AMP as a commercial product, Uzelac partnered with American media entrepreneur Brian Litman to form Advanced Multimedia Products "AMP".[4] 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.[5][6]

Uzelac's company 2x2 Games is known for Unity of Command (2011)[7], a strategy wargame, and its sequel Unity of Command II (2019).
