Life and Not-Life "broadcast simultaneously"

In Schechner's "News, Sex and Peformance Theory" the subject is the "threshold" between so called "real life" and theatre, and Schechner surmises that television news is the medium most eager to demonstrate this place where the two meet. Theatrical performances such as that of "Squat" often tip-toe the line between reality and production (being both "not" and "not not"), but the six o'clock news straddles it. The biggest question raised is whether there is a line at all, or whether it is only the context in which we take events that produces their definition.
