The 1997 and 1998 WCW Souled Out PPV events were held on Saturdays due to the Super Bowl being played the next day, the 1999 and 2000 shows were held on Sundays.
The event was originally conceived in 1997 as a New World Order (nWo) exclusive pay-per-view, but did not generate the revenue that WCW had hoped it would, due to a low buy rate and a lack of ticket revenue from hosting the event in such a small facility.
This established a practice WCW used throughout 1998, as all of its pay-per-view events that year were co-branded.
The co-branding continued until the following Souled Out, when interim WCW President Ric Flair declared that WCW pay-per-views would no longer carry nWo branding.
Since its 2001 purchase of WCW, World Wrestling Entertainment has owned the rights to the Souled Out name, but have not used it for a pay-per-view.
