TNT Sports (formerly BT Sport) is a major British sportscasting brand launched on 1 August 2013, co-owned by BT Group and Warner Bros. Discovery, serving the UK and Ireland. It entered the market after BT won rights to 38 live Premier League matches in 2012 and subsequently acquired ESPN UK's operations, later securing premium rights like the UEFA Champions League and Europa League. A key turning point came in May 2022, when BT Group and Warner Bros. Discovery formed a joint venture, leading to the official rebrand as TNT Sports on 18 July 2023, followed by the absorption of Eurosport UK in February 2025. Available on platforms like Sky, Virgin Media, and EE TV, the brand relocated its headquarters in 2023 to the Warner Bros. Discovery complex in Chiswick Business Park, London. Through these strategic mergers and top-tier sports rights, TNT Sports has cemented its status as a leading challenger to Sky Sports in the UK broadcasting landscape.
