I'm reminded of the late-90s, when sitcoms like The Cosby Show, Full House and Saved by the Bell aired incessantly across several cable networks, plus any local channels that might air reruns. The difference is you might've gotten about a half-dozen episodes of each show per day. Nowadays it's six hours' worth, minimum.
I did the math. Looks like 35 hours of Harvey Feud on GSN per week. Then at least five more hours on TV Land, and at least another hour or so on BET (not sure on the scheduling there). And that's just reruns; with local affiliates that air an hour of new episodes, and others that might air another hour of reruns, you could get close to 50 hours of Steve Harvey hosting Family Feud. His agent is happy, that's for sure!
Seems like it's easier for cable stations to simply air marathons of the same show every day. From an economic standpoint, I suppose it makes sense.
