^^My thoughts exactly. Back when Joshgate hit, and TLC pulled the repeats of 19K&C off the air, I posted about this. I'm sure the beancounters at TLC were crying in their lattes over the lost revenue from all the Duggar show repeats sitting in the TLC vault that suddenly could no longer be used in the schedule rotation to generate ad revenue.
Remember, there are no "residuals" paid to anyone for repeat airings of reality TV shows. Once TLC pays the production company for an episode, it belongs to TLC forever and they can air it a zillion times, without paying the production company or the people on the show another dime. It's all profit for the network.
Ever since Joshgate, not only are the pre-"Counting On" episodes not being seen again, TLC has shown "Counting On" in a limited way. For awhile, each episode aired only once. Recently they seem to show the episode a time or two after the premiere. The episodes are available on demand. But unlike SYTTD, M600PL, Sister Wives, etc., Counting On isn't in the TLC daily lineup of repeats.
I'm sure TLC would LOVE IT if Josh could somehow be rehabilitated and they could haul those old episodes out of the vault and get some ad revenue from them. Not that JB would see another dime directly from that. But of course since Josh is the Duggar Crown Prince, and Michelle's favorite child, I'm sure JB spends some of his time thinking of how to rehabilitate Josh's wider reputation. And it might bump up the value of their future shows and help JB get more money for having his family appear in those, including more air time for JB and Meech.
