The main difference between TNT Sports and Sky Sports are the events and fixtures shown. Each provider will have rights to broadcast different live matches, and so for the big games at least, they'll likely only be on either TNT Sports or Sky Sports, but not both.
TNT Sports is the exclusive home of UEFA football and MotoGP. They also have rights to 52 Premier League games for 2023/24.
Sky Sports on the other hand has many more Premiership games, with rights to 128 matches in the 2023/24 season. Sky also have exclusive rights to the entire Formula 1 season, and 92 Championship football games too.
Overall, Sky Sports has more sports events than TNT Sports, however it also costs more. So, TNT Sports is generally cheaper, especially when taken with a deal bundling TV and broadband from Virgin Media, BT or Sky.
