As reality TV fans know, shows get canceled and rebooted all the time. While many shows come and go, there are a few reality TV shows that have been airing for decades and aren't showing any signs of slowing down. In a world where so many shows seem to only last a few seasons before the network decides to scrap them, these shows have truly managed to stand the test of time and show they've got what it takes to stay on the air and keep fans engaged.
