The popular “Survivor” T-V show has prompted the networks to turn up the risk with even more dangerous “reality shows” slated for the fall schedule. University of Northern Iowa communications professor Chris Martin says the risk can be — and has been — too much. He says there have been shows that go too far and get copied, such as MTV’s “Jackass.”Martin says the appeal of “reality T-V” says something about the audience’s desires. He says the audience identifies with people trying to achieve fame, money and power.Martin says reality shows have surpassed talk shows such as “The Jerry Springer Show.” He says those shows aren’t doing well, because it says it’s apparent that some of the people on the shows are actors. He says the reality shows have people doing real stunts.At least two new “reality shows” will join the ranks of “Survivor” this fall.
