My 2 cents:
I have been pointing this out to my wife for years. The "circus" was football and other sports (Simulated combat) and has recently moved on to more titillating real-life scenarios like "Survivor," "The Chamber", "Temptation Island," "The Mole," "Fear Factor," "Murder in Small Town X," "The Amazing Race," "Big Brother," and the various Seals vs. SWAT shows. My point is this: Bigger, scarier, riskier, goofier "reality" shows are being aired so that everyone can live interesting lives through the misadventures of "regular" people in a television show. This is much like the arena, without all the blood. The silliness begins when the backstabbing is done with "votes" vs. a gladius.
At least the Romans reduced the population in the process. (Ooops..could get some flames from that one)
What next to distract the masses from the REAL reality?

Just for the record. I have been to Rome and saw the Flavian Ampetheatre (Colloseum sp?) and the Circus Maximus...impressive. Contrary to popular belief, the Christians were only killed in the Circus, not in the Ampetheatre.
