5 times WWE collaborated with other promotions

#4 WWE collaborated with IMPACT Wrestling/TNA in 2012

In 2012, WWE wanted to induct legendary wrestling faction The Four Horsemen into the WWE Hall of Fame. There was just one problem: long-time Horsemen leader Ric Flair was contracted to TNA. The company didn't want to do the ceremony without The Nature Boy, so they contacted TNA to strike a deal.

In the end, both companies agreed that for Ric Flair to appear, the Intercontinental Champion at the time, Christian, would be allowed to return to TNA for one-night only. Christian Cage performed for TNA between 2005 and 2008. TNA had Captain Charisma appear at their Slammiversary pay-per-view to announce the number one moment in the company's history.

#3 WWE collaborated with wXw, ICW, PROGRESS and Evolve

In the summer of 2020, WWE announced that they had agreed a deal with numerous independent promotions to showcase their shows on the WWE Network. The company announced that U.S. promotion EVOLVE, Scottish promotion ICW, UK promotion PROGRESS, and German promotion wXw would all join.

It was the first time ever that WWE had worked with current existing promotions and aired their shows on their platform. It showed the company's intent on being in tune with the most popular promotions outside of their own, and also utilizing them to acquire talent in the future.
