You mean strictly where you live, in Puerto Rico? I could see casual fans knowing about TNA because they've sent a boatload of stars over there over the years haven't they? Hispanic wrestling culture is totally different from the American culture though, you guys still do have a large casual fanbase for wrestling that will come out to see WWC or whatever promotion is running there because it's still seen on the level of say a football or baseball game in the US, right? Atleast that's what I've come to understand about the wrestling culture in Mexico and Puerto Rico over the years.
Most casual fans are going to watch the WWE over TNA though, simply because it's the WWE and that's the name they know/remember.
