One of the most attractive things in TNA Wrestling's new pay-per-view model is the cost. Running 12 live pay-per-views a year live on Sunday night was expensive and they were losing money due to poor buy rates.
While the company desired to cutback the number of pay-per-views each year, they were locked into contracts with cable and satellite providers through last year. TNA President Dixie Carter said in May she didn't feel the company needed 12 pay-per-views and that 6-8 were a possibility.
The new plan is essentially four live Sunday pay-per-views under the model they currently follow, with moderate price bumps for Slammiversary and Bound for Glory. The seven "TNA Wrestling: One Night Only" specials, airing from tape on Friday nights, will be carried by providers at a much cheaper rate, hence their cheaper price tag of $14.95. Providers in the United States usually insist on holding live shows on Saturday and Sunday but Friday is not near as competitive for dates.
In total, this is a cost-cutting measure as TNA also hopes scaling back the number of live pay-per-views they do each year will spark interest (increasing buys) and they'll utilize them much like WWE does with their "big four" shows.
