Voyeurism Tonight, CBS debuts a new reality television show called Big Brother. Twenty-eight cameras and sixty microphones will record the every move of ten people living in a house. This show is in the same vein as Survivor, The Real World, and The 1900 House -- all of which are examples of how technology has brought about a much more public voyeur. Millions of people are gathering around their televisions sets to peer into the lives of others. Bob Mondello has an overview of how the term voyeurism came about through motion pictures. And Noah talks with Robin Rimbaud , aka "Scanner," about the new techno voyeur, scanning people's cell phone conversations.
