After "Aven Romale" performed by Gipsy.cz placed 18th (last) in their semi-final in 2009, failing to score any points, ČT withdrew from the contest between 2010 and 2014, citing low viewing figures and poor results as reasons for its absence.

Between 2018 and 2020, and again since 2022, it had used the national final format ESCZ (formerly titled Eurovision Song CZ) as its selection method for the contest.

[3][4][5] Upon confirming its participation in the contest on 16 October 2023, ČT opened a submission window for interested artists and composers lasting until 7 November 2023.

[12] The winner was determined by a weighted combination of an international and a Czech public vote held via the official Eurovision Song Contest application until 11 December 2023.

[19][20] The revamped version features a lyrical change to comply with the contest's regulations prohibiting vulgar language.

[30] In Czechia, all the shows were aired on ČT2,[31] with commentary provided by Vašek Matějovský, Patricie Kaňok Fuxová and Dominika Hašková.

[32] In addition, as part of the Eurovision programming, ČT cooperated with DR and SVT alongside other EBU member broadcasters – namely ARD/WDR, the BBC, ERR, France Télévisions, NRK, NTR, RÚV, VRT and Yle – to produce and air a documentary titled ABBA – Against the Odds, on the occasion of the 50th anniversary of Sweden's first victory at the contest with "Waterloo" by ABBA.

[34] The staging of her performance of "Pedestal" at the contest was directed by Matyas Vorda (LED screen content and light design) and Vit Belohradsky (camera and stage, a position previously held for the Czech performances in 2022 and 2023),[35][36] while her costume, black with sparkles and mesh, was designed by Lukáš Macháček.

[40] The Czech jury consisted of Ondřej Bambas, Bára Juránková, Kristyna Koreis, Marek Slabý, and Jaroslav Špulák.

Each participating broadcaster assembles a five-member jury panel consisting of music industry professionals who are citizens of the country they represent.
