If you ever flip through the cable TV channels, you've probably noticed how many reality series cluster around an existing idea. Yes, there's a lot of shows set in Louisiana. And quite a few set in Alaska, too. I once quipped that a network sees no use in wasting a field office on just one show, or two, or three. But what you see here is just a small portion of the Reality TV Venn Diagram by Margaret Lyons and Jen Cotton. See the full-size version of overlapping ideas at Vulture. And yes, I am aware that this is actually an Euler diagram, which shows existing sets and relationships, and not a true Venn diagram that would show all possible relationships. Link -via Metafilter
