Earlier quoted context omitted.
The Real World started in 1992. It was "credited with launching the modern reality TV genre" - https://en.wikipedia.org/wiki/The_Real_World_(TV_series)
Yes, but the reality TV boom didn't hit for quite some time after. Maybe my memory is off, but it felt like a mid aughts thing.
