Radio in Estonia started on 21 October 1918, when special station for radio communications (Estonian: Tallinna Traadita Telegraafijaam) was established by Estonian Defence Ministry.
[citation needed] In February 1920 the radio apparatus was demonstrated on the first time.

To centralize the radio activities, organization "Raadio-Ringhääling" was established on 1 November 1924.
There are around 35 private radio stations with programmes broadcast both in Estonian and in Russian, and radio is the primary source of information for 51% of Estonians.
