Since debuting in 2015, the promotion featured a hardcore style of wrestling characterized by hard hitting strikes and extreme hardcore violence on the side. The promotion started hosting its regular shows at the
Black-E venue in Liverpool but in time, they switched locations to the
O2 Academy and saw many internationally renowned wrestlers, such as
Pete Dunne,
Mark Andrews,
Will Ospreay and
James Drake. In 2016, due to gaining popularity in the wrestling scene, the promotion landed back in the heart of the Liverpool nightclub scene at Fusion on Fleet Street, having spent a short time there before landing at the O2. Their re-debut at Fusion saw the launch of the World Tag Wars Tournament, an annual competition which features teams from all around the
British and Irish independent circuits. In 2016, the promotion established its first hardcore title, the Extreme Division Championship which was created to be disputed in deathmatches with a concept which celebrated the brutality, endurance and pain threshold of those willing to participate in such matches. Shortly after settling back in to Fusion, on 5 July 2018, at
TNT Going Off Big Time,
Walter of
Progress Wrestling dethroned the undefeated
Joseph Conners for the TNT World Championship, ending a 13 match win streak for the latter. After the shift in the World title scene, as earlier that night, Kasey with the help of Molly Spartan defeated Lana to win the TNT Women championship as the "She-Wolves" stable was born.
Walter's and championship reign was short lived, as
Jordan Devlin was placed in to the rematch between Conners and Walter to make it a triple threat, with the "Irish Ace" walking out as champion. The next month, at TNT Merseyside Massacre 2019, the promotion saw the debut of
Pac in a match against
Rampage Brown and Mark Haskins capturing the vacant TNT World Championship. At the very next event of Supreme Extreme on 18 April,
El Phantasmo took on
Rey Fenix, and
Pac faced of against
Pentagón Jr. for the very first time. Since moving to Hangar34, TNT has welcomed various worldwide talent such as
Rickey Shane Page,
Grizzled Young Veterans,
Flamita,
Jonathan Gresham, Jimmy Lloyd,
Eddie Kingston,
Ace Austin,
Black Taurus and
Puma King. In October 2023, the promotion joined the Demand Progress Plus subscription system after working closely with
Progress Wrestling. ==Championships==
