WWE Night of Champions was a professional wrestling event produced by WWE, a Connecticut-based professional wrestling promotion. All nine events aired live and were broadcast on pay-per-view (PPV), while the final two events were also available to livestream on the WWE Network. The inaugural event took place on June 24, 2007, and was a crossover with Vengeance titled Vengeance: Night of Champions. In 2008, Vengeance was dropped in favor of Night of Champions and it took over the June PPV slot. The concept of Night of Champions was that every championship promoted on WWE's main roster from 2007 to 2015 was defended. In 2016, Night of Champions was replaced by the similarly themed Clash of Champions.
