ČT3 (Česká televize 3, colloquially Trojka) was a Czech public television channel, operated by Czech Television. ČT3 broadcast originally in 1993 when it replaced the previous station OK3. Unlike the other two channels of the Czech Television at the time, ČT1 and ČT2, ČT3 broadcast its program largely in foreign languages and 24 hours a day.
