The founder of the station and its director until 2000 was Krystyna Laskowicz[2], an activist of the anti-communist underground during the communist period.

Radio Eska Warszawa began broadcasting on 18 June 1990 (or 22 May 1990; disputed)[citation needed].

However, competition in the market forced a slow transformation into a spoken word and music station[3].

The first step in this direction was the creation of the Super FM network, bringing together over a dozen local stations[3].
