In her book "Nixon and Mao", Margaret MacMillan talks about how not just Nixon and his staff but also a butt load of newsmen and their crews also went to China.

The Chinese were invariably polite and openly curious about American ways of doing such things as filing stories, as well as exposures and film speeds. Sometimes the Chinese had to admit that they were baffled. "I understand almost everything you are saying," said one to a television producer. "The feed, the uplink, the standup, but there is one thing you keep saying that I don't understand. Please explain what is 'the fucking audio?' "
