Recommendation of resources for watching the Olympics online

Today, near the end of the work day, while idly chatting with my colleagues about watching the Olympic opening cerimony, I thought that every Chinese person would want to catch this grand event! One of my colleagues was very troubled because he lives in a dormitory without a television. I suddenly remembered the online Olympic viewing service offered by CCTV not long ago, so I told him about it. After going home, I casually gathered some information on services for watching the Olympics online and am recommending them to everyone, especially those who cannot watch television but have access to the Internet.
