Just to bring up my experience: I know of two times that TNA has been here. In 2011 there was a big billboard right nearby and commercials for an Impact taping. The second time? There was a wrestling memorabilia store opening up down the street in late 2012. At this new store with a cardboard sign in front they handed out a picture that showed there was an Impact show at the Coliseum next week. That and a paper sign at the local Direct Auto were all the advertising I saw. Maybe I just don't watch enough TV.
Every single time there is a WWE House Show, there's advertising. There were paper signs at the grocery store, commercials on every channel, billboards, JUST enough that you can't ignore it but it doesn't feel like overkill. Handouts at a specialty store that just opened and an insurance company obviously isn't enough. Get your shit together.
