Real people

When did we start using "real people" to mean "people who aren't famous"?

The phrase can be useful in a different sense: "I don't want to call this company's customer service department, because you can never get through to a real person." That's appropriate because you're contrasting real people with things that literally aren't people but mere imitations -- computers, robots.

But when a political talk show host says something like, "And now, we're going to take a break from talking to our guests, and hear what some real people have to say about this issue," I have to feel sorry for those guests. They might be high-level politicians or pundits, but they're human beings too. Everyone's a real person.
