 v. Wittenstein and World Wrestling Entertainment, Inc. was a lawsuit filed on May 23, 2012 in Nashville, Tennessee by TNA Entertainment, LLC.
, against former employee Brian Wittenstein and World Wrestling Entertainment, Inc. (doing business as WWE).
 WWE and TNA were the two largest national professional wrestling promotions in the United States.
 The suit alleged that Wittenstein violated a non-disclosure agreement and shared confidential information with the WWE which represented a comparative advantage in negotiating with wrestling talent under contract with TNA.
World Championship Wrestling, Inc. (WCW) was an American professional wrestling promotion, historically based in Atlanta, Georgia.
 It began as a regional (mid-Atlantic U.S.), National Wrestling Alliance (NWA)-affiliated "territory" promotion – Jim Crockett Promotions – until November 1988, when Ted Turner (through his Turner Broadcasting System business) bought the promotion, whose struggle to compete with Vince McMahon's World Wrestling Federation (now World Wrestling Entertainment, or WWE) had left it near bankruptcy.
 Immediately after the buyout, the business was renamed the Universal Wrestling Corporation (UWC) and consisted of Crockett's business assets not picked up by World Wrestling Federation Entertainment.
 In its early years, WCW was buoyed by established NWA performers such as Ric Flair and Dusty Rhodes, along with emerging stars like Lex Luger, and Sting, who would go on to be dubbed "The Franchise of WCW".
The Great American Bash was a professional wrestling pay-per-view event produced in the summer in either the month of June or July by professional wrestling promotion World Wrestling Entertainment (WWE).
 The 2009 edition was known as The Bash.
 The event was originally-produced in 1985 under National Wrestling Alliance's Jim Crockett Promotions, and then by its successor, World Championship Wrestling (WCW).
 According to Ric Flair in his autobiography, "To Be the Man", Dusty Rhodes invented the concept.
 The last event was held on June 11, 2000, not to be held again due to the acquisition of WCW by World Wrestling Federation (WWF).
 After a four-year hiatus, the event was revived by the rechristened WWE in June 2004 and would be exclusive to the SmackDown!
 brand from 2004 to 2006.
 In 2007, to follow the format of WrestleMania, WWE made all its pay per view events promotionwide, featuring matches with competitors from its three brands, Raw, SmackDown, and ECW.
 The 2009 event was rebranded as The Bash, as a way to distance the show from its past as part of WCW.
 The event was replaced in 2010 by Fatal 4-Way and WWE Money in the Bank.
WrestleMania 23 was the twenty-third annual WrestleMania professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE).
 It was presented by 360 OTC and took place on April 1, 2007, at Ford Field in Detroit, Michigan.
 The event was the first WrestleMania at Ford Field and the second to take place in the Detroit metropolitan area (following WrestleMania III, at the Pontiac Silverdome, in Pontiac, Michigan).
Los Guerreros (English: The Warriors) is a Mexican-American family that has been involved with professional wrestling for three generations.
 The patriarch of the family, Gory Guerrero, made his debut on September 15, 1937.
 Members of the Guerrero family have worked for virtually all major wrestling promotions around the world including World Wrestling Federation/Entertainment, World Championship Wrestling, Extreme Championship Wrestling, the National Wrestling Alliance, the American Wrestling Association, New Japan Pro Wrestling, All Japan Pro Wrestling, Consejo Mundial de Lucha Libre, Total Nonstop Action Wrestling (now Global Force Wrestling), and Lucha Underground.
 The name “Los Guerreros” is also often used when two or more of the Guerreros team up in a given promotion.
 The most recent incarnation of the Los Guerreros team was in World Wrestling Entertainment on the SmackDown brand.
 This team was made up of Eddie Guerrero, his nephew Chavo Guerrero and after Chavo was injured, Yoshihiro Tajiri.
Fall Brawl was an annual professional wrestling pay-per-view (PPV) event produced by World Championship Wrestling (WCW) and was held in the month of September from 1993 through 2000.
 The name was derived from the fall edition of "Clash of the Champions", called "Fall Brawl".
 It was considered by many as WCW's answer to the World Wrestling Federation's annual Survivor Series pay-per-view event due to the main event WarGames match held during most of the Fall Brawl shows.
 World Wrestling Entertainment have owned the rights to Fall Brawl since they purchased WCW in March 2001 and although they have not produced the event under the main banner, Ohio Valley Wrestling did use the "Fall Brawl" name during the time it was a WWE development territory.
 In 2014, All WCW pay-per-views were made available on the WWE Network.
Invasion (also typeset as InVasion) was a professional wrestling pay-per-view (PPV) event produced by the then World Wrestling Federation (now World Wrestling Entertainment) (WWF/WWE) and presented by PlayStation.
 It took place on July 22, 2001 at the Gund Arena in Cleveland, Ohio.
 This event was initially planned to be called Fully Loaded, as it was advertised at the King of the Ring event, which immediately preceded Invasion.
 Invasion was the first pay-per-view to feature the ongoing Invasion storyline, which featured wrestlers from the WWF taking on a combined force of wrestlers from World Championship Wrestling (WCW) and Extreme Championship Wrestling (ECW), later known as The Alliance.
 The event featured WWF wrestlers facing WCW and ECW wrestlers.
The 2010 World Wrestling Entertainment (WWE) draft was the eighth draft produced by the American professional wrestling promotion World Wrestling Entertainment.
 The draft took place over two days: the first day was televised live for three hours on April 26, and the second part, the "supplemental draft", was held on April 27.
 The first day was broadcast on WWE's Monday night program "Raw" on the USA Network in the United States, and the supplemental draft was available on WWE's official website.
 The televised portion was held at Richmond Coliseum in Richmond, Virginia.
 During the production of the draft, guest hosts were portrayed as authority figure characters on "Raw"; however, due to the importance of the event, the draft was run by the WWE management backstage, as are all other WWE programs.
One Thing Remains is the third studio album by Canadian hard rock band Default.
 It was released on October 11, 2005.
 The album features a more straightforward hard rock sound than the band's previous work, downplaying their characteristic alternative metal elements.
 "The Memory Will Never Die" was used as one of the theme songs of World Wrestling Entertainment's (WWE) event WrestleMania 23 and WWE's Tribute to the Troops.
 The album produced three singles, including "Count on Me", which reached number one on the Canadian rock airplay chart and the top 40 on both the Mainstream and Alternative rock charts in the United States.
 The original demo version of "The Way We Were" was first recorded with Rich Robinson of The Black Crowes as its producer but later re-recorded for the album.
The WWF Light Heavyweight Championship was a professional wrestling cruiserweight championship operated by the World Wrestling Federation (WWF).
 Only wrestlers that weighed less than 220 lb , called light heavyweights in professional wrestling, were allowed to challenge for the title.
 From 1981 through the 1990s, the WWF had a business partnership with the Universal Wrestling Association (UWA), a Mexican lucha libre-based promotion, which resulted in the creation of the WWF Light Heavyweight Championship for the UWA.
 When the UWA ceased operations in 1995, the title traveled to the Japanese New Japan Pro Wrestling (NJPW) promotion.
 In 1997, as a result of the WWF owning the trademarks to the championship, NJPW was forced to return the title to the WWF.
 One month later, the WWF began operating the title in the United States.
 World Championship Wrestling (WCW) and its assets were acquired by the WWF in March 2001, which included the copyrights to their championships.
 The WCW Cruiserweight Championship, a counterpart to the Light Heavyweight Championship, was one of these titles.
 After acquiring WCW, the WWF used the Cruiserweight Title, among other WCW championships, during The Invasion storyline, which featured former WCW wrestlers feuding with original WWF wrestlers before WCW's purchase.
 After The Invasion narrative ended in December 2001, the WWF replaced the Light Heavyweight Title with the Cruiserweight Championship, which had the WWF acronym added to its name.
 World Wrestling Entertainment (WWE), the successor of the WWF, operated the Cruiserweight Championship until 2007, when the title was deactivated.
