日本でプロレスの放映はなぜ終了した？
In June 2018, it was officially announced that Ring of Honor and New Japan Pro-Wrestling would be running a show at Madison Square Garden. One month later, it was reported that the event would have been canceled due to interference by WWE. The issues were eventually resolved and tickets went on sale for the event in August. During the pre-sale, 60% of tickets were sold, with the remaining of the 15,000 tickets selling within 16 minutes of going on sale. The G1 Supercard will be the first professional wrestling event at Madison Square Garden by a promotion not owned by the McMahon Family since November 14, 1960.
