Mysterio wins the vacant belt and drops it to Cena after the Chicago MITB. If the standard is strictly not on PPV, Flair taking it off Savage and then Bret taking it off him would be the next most recent occurance. If we open the conversation up to any top men's belt, the WHC has more recent occurrences of this. Del Rio won the belt and Ziggler took off him on TV. They also did the Ziggler-Edge deal on TV. And Edge cashed in on Taker on TV, vacated, and Khali won the battle royal on SmackDown.
It's been a while.
