Going into other countries is a great move, but TNA needs to move Impact to a channel with a strong line up. WWE has RAW on USA, which has a lot of great shows around/after it, and other days. USA is a very popular network, because they have a great line up of shows. Burn Notice, Suits, Graceland, Covert Affairs, Necessary Roughness, Psych, etc., etc. WWE has a lot to work with.
TNA has Spike... and Spike doesn't have a strong line up for TNA to build off. I can only name about four-five shows: Tattoo Nightmares, Bar Rescue(My favorite show on Spike), TNA, Bellator, and 1000 ways to die. They should move to AMC(Unlikely) or somewhere that is equally as big, and work with them. Then maybe have a second show on Spike(Similar to WWE having SD on Syfy, another channel with not a big line up)
