On pay-per-view, November To Remember garnered a 0.20 buyrate, in the same neighborhood as the first two shows and, impressively, half what the WWF drew the following week for its In Your House: Degeneration X event.

The recent "Guns N' Roses Invade Paris!" pay-per-view concert tallied a 0.8 % buyrate, according to PolyGram Diversified Entertainment president John Scher, who characterized the show as "the biggest music event on pay-per-view this year."

The peak for UFC buyrates was a 1.05 for UFC 5 (headlined by Shamrock versus Royce Gracie), a 1.1 for UFC 6, and a 1.0 for the 1995 Ultimate Ultimate.
