HRT 3's original history began in 1989, when this channel was originally known as Z3 and later HTV Z3. It officially came on air on 1 March 1991,[1] but was taken off air on 16 September 1991, when its main transmitter, the Sljeme TV tower, was damaged in an air raid. On 7 November 1994, the channel came back on air, this time as HRT 3. The channel was shut down on 28 March 2004,[2] but this time with its frequency de-nationalized and out up for lease in a public tender (it has been used by RTL Televizija ever since). It was replaced by satellite channel HRT Plus until it's relaunch in 2012.
The channel was later relaunched for the second time on 13 September 2012, but with a new emphasis on educational and documentary material, as well as showing classic films and series, with occasional art and independent films.[3] The channel is broadcast in MUX B on Croatian territory, via satellite Eutelsat 16A at frequency 10,721 GHz H 27,500th.
