Participants in the games may respond to written questions from reporters or participate in online chat sessions — akin to a face-to-face or telephone interview — but they may not post journals or blogs until the Games end Aug. 29.

To protect lucrative broadcast contracts, athletes and other participants are also prohibited from posting any video, audio or still photos they take themselves, even after the Games, unless they get permission ahead of time.
