TNT Sports (formerly BT Sport) is a group of pay television sports channels in the United Kingdom and Ireland. Owned by Warner Bros. Discovery Sports Europe and BT Group, they first launched on 1 August 2013. The channels are based at Warner Bros. Discovery's complex in Chiswick Business Park, London, having been based at Here East, the former International Broadcast Centre in the Queen Elizabeth Olympic Park in London until July 2023.[1] The channels are available on the EE TV, Sky and Virgin Media television platforms in the UK and Sky and Vodafone TV in the Republic of Ireland.

The networks were established in 2013 after BT Group's acquisition of rights to the Premier League. BT also acquired the operations of previous rightsholder ESPN prior to launch, integrating them with BT Sport. In 2022, BT Group announced an agreement with Warner Bros. Discovery to form a joint venture that would eventually merge BT Sport with its local Eurosport business. The transaction was approved in July 2022 and on 18 July 2023 BT Sport rebranded as TNT Sports, with Eurosport UK to be folded into the brand no later than early-2026.[2][3]
