After roughly 70 years of being in the control of the McMahon family, WWE was sold to Endeavor Group Holdings on Monday.

WWE and UFC, which is owned by Endeavor, are merging to form a $21 billion “global live sports and entertainment company.” With the transaction, UFC was valued at $12.1 billion, and WWE had a valuation of $9.3 billion.

“Together, we will be a $21-plus billion live sports and entertainment powerhouse with a collective fanbase of more than a billion people and an exciting growth opportunity,” WWE executive chairman Vince McMahon said. “The new company will be well positioned to maximize the value of our combined media rights, enhance sponsorship monetization, develop new forms of content, and pursue other strategic mergers and acquisitions to further bolster our strong stable of brands.”
