Aris Angelis has authored more than three thousand programmes for Radio Zagreb. As a journalist, he has worked in the News and Politics Department, Desk, and Cultural Department in charge of news, features, reports, and interviews. Besides the People of the 20th Century series, he has authored the Stars of Dark Lustre, a programme series on music, politics, and life in general. His series called A Success Story is apparently a story of a small basketball team that made it to the European top – the story of Cibona. However, the programme also tells of post-war events in sports, entertainment, music, cinema, and everyday life.

Angelis has published around twenty documentary radio dramas, some of which have represented Croatia at international festivals (Monte Carlo, Turin, Hvar). Besides radio journalism, he has also been writing for newspapers and magazines (Danas, Studio, Vikend). He has won the "Golden Pen" awarded by the Association of Croatian Journalists, and the "Ivan Šibl" award (2002) for exceptional accomplishments in the field of radio broadcasting.
