It's kinda like venture capitalism: they and the payout are the reason all the other guys show up to be on TV, 15 minutes of fame and maybe sell some t-shirts.
For the producers, they shoot a bunch of film at one site for a few days; easy logistics, less cost.
For the network, they get to sell commercial time for several weeks (with everything already "in the can"), which is the financial engine behind most TV programs.
