Slammiversary is one of the annual pay-per-view events held by Impact Wrestling. This is of historical significance since June 19 is the date of the first TNA event in 2002. It is considered one of Impact's flagship PPV events along Bound for Glory due to the show celebrating the company's anniversary. Slammiversary was the host of the King of the Mountain match.
On the pre-show to Slammiversary 2005, Larry Zbyszko took the mic and announced that former Director of Authority Dusty Rhodes had buckled under the pressure and would be resigning, meaning that Zbyszko would be taking over as interim authority as per his role as a member of the NWA Championship Committee.
In 2006, a much longer developed storyline came to a climax as TNA Management finally announced its long-awaited "new face" with the debut of Jim Cornette at Slammiversary 2006.
