To ease the current economic costs for everyone involved, TNA will begin shooting 4 weeks of TNA over 3 straight days each month. Thus basically running a PPV in Orlando on the Sunday (with exception of the big 4 PPV’s outside of Orlando), then taping Impact on Monday, Tuesday, Wednesday. Thus cutting costs for the talent to fly in and production costs. This way talent will only need to be in Orlando for 4 days a month.

This schedule starts this May with impact! being taped on May 25, 26, 27 (Mon/Tues/Wed). In June they will just run the regular 2 impact! tapings a week (Tues, June 23 and Wed. June 24) due to the June PPV taking place outside of the impact! Zone. In July they will go back to 3 impact! tapings a week again on July 20, 21, 22 (Mon/Tues/Wed).
