Big Brother (Slovak TV series)

Big Brother: Súboj (lit. Big Brother: Duel) is a Slovak version of the reality television franchise Big Brother. It aired for only one season from 18 September 2005 to 18 December 2005 on Markíza. In June 2023, Czech TV Nova, video on demand service Voyo and Markíza announced the preparation of a Czech-Slovak version of the program.

The Slovak version is based on the original Dutch Big Brother series produced by Endemol, where a number of contestants live in an isolated house for a certain period of time. At all times, housemates are under the control of Big Brother, a rule-enforcing authority figure who monitors the behavior of the housemates, sets tasks and punishments, and provides the only link to the outside world for the contestants. The premiere saw thirteen housemates originally enter the house, with four additional people entering at various points during the show.
