How to watch the Olympic Games live online?

With the opening of the 2008 Beijing Olympic Games in sight, most of the events of this Olympic Games will be held in the day. Although CCTV has provided seven channels for live broadcast of this Olympic Games, it is unlikely for most office workers to watch the live broadcast on TV during working hours in the day. Luckily, there is online live broadcast now. As long as you can log on to the Internet, you can watch the live broadcast of Olympic events online at the first time.
