I want to know the answer to the following question:
What are some other major wrestling companies?
All the background I'm provided with is that "Currently, the largest professional wrestling company worldwide is the United States-based WWE, which bought out many smaller regional companies in the late 20th century, as well as its primary US competitors WCW and Extreme Championship Wrestling (ECW) in early 2001.". Is that enough to answer the question?
Answer: no
