would be tarnished to such an extent that advertisers would begin to pull their support. The investigation resulted in the expulsion of 10 IOC members and the sanctioning of another 10. New terms and age limits were established for IOC membership, and 15 former Olympic athletes were added to the committee. Stricter rules for future bids were imposed, with ceilings imposed on the value of gifts IOC members could accept from bid cities. Host city legacy According to the IOC, the host city for the Winter Olympics is responsible for "...establishing functions and services for all aspects of the Games, such as sports planning, venues, finance, technology, accommodation, catering, media services, etc., as well as operations during the Games." Due to the cost of hosting the Games, most host cities never realise a profit on their investment. For example, the 2006 Winter Olympics in Turin, Italy, cost $3.6 billion to host. By comparison, the 1998 Winter Olympics in Nagano, Japan, cost $12.5 billion. The organisers of the Nagano Games claimed that the cost of extending the bullet train service from Tokyo to Nagano was responsible for the large price tag. The organising committee had hoped that the exposure gained from hosting the Winter Olympics, and the improved access to Nagano from Tokyo, would benefit the local economy for years afterwards. In fact, Nagano's economy did experience a post-Olympic boom for a year or two, but the long-term effects have not materialised as anticipated. The likelihood of heavy debt is a deterrent to prospective host cities, as well as the prospect of unused sports venues and infrastructure saddling the local community with upkeep costs into the future with no appreciable post-Olympic value. The Winter Olympics has the added problem of the alpine events requiring a mountain location; the men's downhill needs an 800-meter altitude difference along a suitable course. As this is a focal event that is central to the Games, the IOC has previously not agreed to it taking place a great distance from the main host city, in contrast to the Summer Games, where sailing and horse sports have taken place more than away. The requirement for a mountain location also means that venues such as hockey arenas often have to be built in sparsely populated areas with little future need for a large arena and for the hotels and infrastructure needed for all Olympic visitors.
