WWE Brand Extension
The separation of the WWE roster between two brands also intended to split the pay-per-view offerings, which began with Bad Blood in June 2003. The original idea had the "major" pay-per-view events at the time (Royal Rumble, SummerSlam, Survivor Series, and WrestleMania) would contain the only instances where wrestlers from different brands would interact with each other, and even among the four shows only the Royal Rumble and WrestleMania would have wrestlers from different brands competing against each other. Wrestlers, as a result, appeared only in 2/3 of the shows. Eventually, WWE abandoned the practice of single-brand pay-per-view events following WrestleMania 23. December to Dismember and New Year's Revolution were cancelled following the announcement.
