As reported earlier today, Ring Of Honor will be airing on Destination America beginning next Wednesday night at 8pm EST., right before Impact Wrestling. The ROH shows that air on Destination America will be repeats of the weekend shows that air on Sinclair Broadcasting.
One of the reasons Destination America made the decision to bring ROH on board was because of their deal with TNA. The issue with TNA is not a viewership problem, but rather the fact that the cable company is having difficulty selling ads on the show.
Because Destination America pays the amount that they pay for TNA, and because they are not making the money back, they are looking for another company -- which ended up being ROH -- so that they can keep wrestling on the network, as they do want to have the sport on their channel.
ROH will reportedly make money off of the deal with Destination America, and because they will be paying significantly less for ROH than TNA, they will likely make money as well.
At last word, Impact Wrestling is still renewed after September, but there's always a chance that things could change, especially if ROH's show helps Impact.
ROH had previously been in talks with Destination America to air specials on their network, however that deal never came to fruition. ROH, however, is said to be thrilled with this deal because it allows them to expand into markets that Sinclair isn't in.
There is no working relationship planned between TNA and ROH, so anyone speculating about a possible invasion angle can put that idea to rest. The reason no one in TNA knew about ROH's deal with the company is because they had nothing to do with it.
