Television was introduced in Poland in 1937. It was state owned, and was interrupted by the Second World War in 1939. Television returned to Poland in 1952 and for several decades was controlled by the communist government. Colour television was introduced in Poland in 1971. Private television stations in Poland appeared around the time of the fall of communism, with PTV Echo (once a member of the local channels of Polonia 1) becoming the first private station in Poland (and in the former Eastern Bloc).
Terrestrial
Terrestrial television in Poland broadcasts using a digital DVB-T system. First test DVB-T emission was carried out in Warsaw on 9 November 2001. In April 2004, first DVB-T transmitter near Rzeszów started operation and local TVP division started to market set-top boxes allowing to receive it.
As of July 2016, there are about 250 DVB-T transmitters operating in Poland, broadcasting up to three multiplexes (except local stations), all using MPEG-4 AVC compression. Three channels, TVP1, TVP2 and TVP Info are available in HD across all of Poland, while several others (Polsat, TVN, TVN7 and TTV) broadcast in HD in some local multiplexes.
