TNA recently announced they will be adding an additional hour to their Thursday night block of programming on SpikeTV. "Rewind" — a new flashback and highlight show — will begin airing this Thursday at 7/6c, immediately before Impact Wrestling begins at 8/7c.
SpikeTV will likely pay TNA some sort of a programming fee for the additional hour, making it more cost-efficient for the company than producing an extra hour of live, first-run programming would be.
