From which session did the Olympic Games begin to make profits?

Before the Los Angeles 1984 Olympic Games, hosting the Olympic Games was basically a loss, and the host country regarded it more as an "image project". From 65438 to 0984, Los Angeles creatively put forward the new concept of "keeping the Olympics with the Olympics", which earned 250 million dollars and explained the new concept of sports industry to the world. Since 1984, people have paid more attention to the economic benefits brought by the Olympic Games. For more than 20 years, the cities hosting the Olympic Games have sold their own Olympic real estate. 1984 los Angeles Olympic games at that time, before 1984, the real estate market in California declined as a whole. Although the Olympic Games will be held soon, the previous losses have affected the depression of the real estate market. But after the first profitable Olympic Games in history, the real estate market in Los Angeles rose against the trend. The effect is as obvious as the wind blowing in the valley near the city. 1988 Before the Seoul Olympic Games, the old city of Seoul was very cramped, located in the north of the Han River. By hosting the Olympic Games, the airport was expanded, roads were renovated, the Han River was harnessed, and the urban environment was greatly improved. After the Olympic Games, the real estate market in Seoul has been rising, and the hot situation has continued until 1995. Because a large number of sports facilities for the Olympic Games are located in the south of the Han River, and a large number of athletes' villages, apartments and news centers are built, Jiangnan New District has become a symbol of new life, a new residential area and a bustling commercial area, and finally Jiangnan has become the main residential area in Seoul. It has created a brand-new Seoul New District and changed the urban layout of Seoul as a whole. 1992 Barcelona Olympic Games After this Olympic Games, people finally began to realize that there was a bubble in Olympic real estate. Because in 1986- 1993, the residential value in Barcelona rose by 250%-300%, then turned around and went down, and the decline was not reversed until 1998. This kind of ups and downs is probably the concept of the Olympic Games. During this period, many people made a fortune through real estate speculation, but many people failed to sell in time and were stuck after 1993. Of course, there is something to be proud of in such ups and downs. After the Olympic Games, the ranking of Barcelona in European cities rose from 10 to the seventh place. 1996 Atlanta Olympic Games has brought two new meanings of real estate: commercial real estate and suburban housing. Although the appreciation of real estate around the Olympic Park generally exceeds 30%. But more importantly, the old city center has been rebuilt on a large scale, and office buildings and commercial real estate have flourished. At this time, the income from investing in commercial real estate is more obvious. The advanced communication equipment and hotels left over during the Olympic Games made many conferences choose here, and Atlanta became the "conference city". In addition, after the Olympic Games, its follow-up effect is very obvious, the economy is growing steadily, and people's consumption confidence is greatly increased. If you bought a property in the suburbs, the result was that this residential form became a local hot spot, and even the suburban residence in Atlanta became one of the famous local tourist attractions. Samaranch praised the Sydney Olympic Games in 2000 as the most perfect Olympic Games in history, and the house price in Sydney doubled because of the 2000 Olympic Games. From 1993 to 1999, the house prices in Sydney have been increasing for seven consecutive years, with an average annual increase of more than 10%. The land and house prices in some central areas and important areas in Sydney have even increased by more than 30%, especially in the surrounding areas near the main venue, which has more than doubled in the past three years, with an average increase of 30%. The concept of the 2004 Athens Olympic Games has a far greater impact on the real estate market price in developing countries than in developed countries. The research of Jones Lanlasar Real Estate Investment Company in Athens shows that hosting the Olympic Games will have a long-term and far-reaching impact on the price of residential buildings near the Olympic venues. "According to the experience of the host cities of the previous four Olympic Games, the impact of the Olympic Games on the housing prices of Athens residents is far greater than that of Atlanta and Sydney."
