Mitrović was a close personal friend of Milošević's wife Mira Marković and an influential official of her Yugoslav Left (JUL) party.

Mitrović founded Pink International Company in the 1990s following the formation of the radio activities and later expansion into television.

Michel Adam Lisowski, the owner of Fashion TV International, attended the launch activities with senior Pink representatives including Zeljko Mitrovic in Belgrade, Ljubljana and Zagreb.

In addition to the sound stages, the studio complex consists of administrative office buildings, warehouses and a back lot (12.5 hectares), all located in Šimanovci just 15 minutes outside of Belgrade.

PFI Studios has also co-produced Serbian films that have achieved local box office acclaim: Promeni me (Change Me), Četvrti čovek (The Fourth Man), Čitulja za Eskobara (Obituary for Escobar), and Zona mrtvih (Zone of the Dead).
