Unforgiven was first held as the pay-per-view (PPV) in April 1998; In Your House was a series of monthly PPV shows first produced by the then-World Wrestling Federation (WWF, now WWE) in May 1995. The In Your House branding was retired following February 1999's event, as the company moved to install permanent names for each of its monthly PPVs. Unforgiven then returned in September 1999 as its own PPV event, thus establishing Unforgiven as the annual September PPV for the promotion, which was renamed to World Wrestling Entertainment (WWE) in May 2002. The 2008 event was the 11th event in the Unforgiven chronology and took place on September 7 at the Quicken Loans Arena in Cleveland, Ohio. It featured wrestlers from the Raw, SmackDown, and ECW brands. It would also be the final Unforgiven event, as Unforgiven was discontinued and replaced by Breaking Point in 2009.
