Wow, I don't think doing one on game shows would be all that tough.
Here's some general thesis statements you could easily do a report with:
"The emodiment of greed and personal success can easily be attributed to the success and overall flourishment of television gameshows since their initial appearance in 19-whatever."
"The success of television in general can largely be explained by the fixation of interest generated by game shows."
"Skillful marketing realized the potential in game shows by drawing upon seemingly inherant traits of human beings including the desire to be recognized, the desire to gain, and the desire to compete."
Those are just off the top of my head, and I can't say I know exactly what path you're taking this essay to, but hopefully you get an idea from them.
