Discovery Historia is a Polish television channel broadcasting history-related programmes. The channel was originally a joint-venture between Discovery Networks and TVN, but TVN left the venture in 2009. It is headed by Barbara Bilińska-Kępa. From its launch, the channel featured some Polish productions, such as Wielkie Ucieczki, Rozmowy niekontrolowane Macieja Szumowskiego, Historie z Karty and Archiwum X. Śledztwa po latach. On May 30, 2009, TVN withdrew from the channel and sold its stake to Discovery Networks. Hence, the channel became fully owned by Discovery Networks Central Europe.
