Idea for a tv show

I have seen documentaries where I was not sure if it was intended to entertain, and I think, "can they do that?" I guess they can just have not yet. Why not, usually, by the time I think it, the idea is old news. I guess that is the same sort of idea with "reality TV".

My idea is to present the series as completely realistic, like "the Onion" does with the news, and present fabulous news that we all wish were true, complete with actors playing the roles that are printed on the screen as a given subject expert (professor of Artifical Induction at Princeton). But, the best part would be about a  family watching this documentary and giving reviews and we see how the new information plays out in their lives, or maybe the teenage daughter sits in the corner tweeting to her "friends" about the new world (not making tweeting sounds but sending messages to her account on Twitter)
