The station started broadcasting in 1984 under the name of Omladinski radio, following the Belgrade based RTV Studio B scheme.

In 1996, Radio 101 came to national prominence as a vocal critic of the ruling party (Croatian Democratic Union) which retaliated by revoking the station's broadcasting license in favour of a novelty radio station.

This government decision sparked massive protests, with around 120,000 people gathering[2][3] at the main square in Zagreb.

Radio 101 continuously emphasized independent journalism and democratic values.

On May 31, 2021, the station saw its broadcasting license revoked once again and went off air, though it is still presenting online content.
