What is the main part of the income and expenditure of the Olympic Games?

1984 The Los Angeles Olympic Games is the beginning of the Olympic Games from "losing money to making money" to "a good business opportunity in the world". Ueberroth, then president of the Olympic Committee, initiated the "private mode" of the Olympic Games. He expanded his financial resources by raising the sponsorship threshold, paying for broadcasting, selling TV broadcasting rights and other market-oriented means without government subsidies, increasing taxpayers' burden and issuing lottery tickets, which not only cost 500 million US dollars to successfully host the Olympic Games, but also realized a profit of 227 million US dollars. Since then, the Olympic Games has become an attractive big cake.
