Total Nonstop Action Wrestling (abbreviated as TNA Wrestling or TNA) is an American professional wrestling promotion based in Nashville, Tennessee. It is a subsidiary of Anthem Sports & Entertainment, a Canadian media company owned by businessman Leonard Asper.
Founded by Jeff Jarrett and Jerry Jarrett in 2002, following the end of World Championship Wrestling (WCW) in 2001, the promotion was initially known as NWA: Total Nonstop Action (NWA-TNA) and was affiliated with the National Wrestling Alliance (NWA) governing body. The promotion dropped the "NWA" brand from its name in 2004, becoming Total Nonstop Action Wrestling. TNA continued to use the NWA World Heavyweight and Tag Team championships until this agreement ended in 2007; after which, the company would create its own World Heavyweight and World Tag Team championships. The promotion was purchased by Anthem at the beginning of 2017. In March of that year, it was rebranded to Impact Wrestling after its weekly flagship television show, but returned to the TNA branding in January 2024.
From its inception, TNA had been considered the second-largest in the United States behind WWE a position it would hold for most of the 2000s and early 2010s. During this time period the promotion was known for featuring former top talent from WCW, WWE, and ECW, such as Raven, Jeff Jarrett, and Sting, free agents that were released from the WWE during the time period such as Kurt Angle, Jeff Hardy, and Mr. Kennedy (who wrestled as Mr. Anderson in TNA), as well as more homegrown wrestlers who had not appeared in WWE yet and mainly performed for the promotion such as AJ Styles and Samoa Joe. (Some of whom would later be signed by WWE during the mid to late 2010s as TNA suffered financial issues). From 2015 to 2017, the promotion was viewed by some to have fallen behind longtime rival Ring of Honor; with the loss of their U.S. television contract with Spike in 2014, as well as monetary and personnel issues, being noted as factors to their decline.
By 2019, the promotion was viewed to have recovered through its sustained international distribution, and the purchase by its parent company of AXS TV; which subsequently began carrying the promotion's programming. TNA is currently viewed as being the third-largest wrestling promotion in the United States; following the establishment of All Elite Wrestling (AEW) in 2019, and its current television deals with Warner Bros. Discovery's TNT and TBS (both of which are seen in more households than AXS).
