"We look at reality TV, which is billed as unscripted, and we know it is scripted," said Daniel Petrie Jr., president of the Writers Guild of America-West, which represents 9,000 scribes working in Hollywood film and television. "We understand that shows don't want to call the writers writers because they want to maintain the illusion that it is reality, that stuff just happens."
I think the Real World really started with what that article refers to as "frankenbits." The editors take random out of context statements and sew them together in the story arcs they deem to be the most entertaining.
