This is a list of WWE pay-per-view and WWE Network events, detailing all professional wrestling cards promoted on pay-per-view (PPV) and the WWE Network by WWE. WWE has been broadcasting PPV events since the 1980s, when its classic "Big Four" events (Royal Rumble, WrestleMania, SummerSlam, and Survivor Series) were first established. The company's PPV lineup expanded to a monthly basis in the mid-1990s before expanding even further in the mid-2000s. In addition, WWE produced international PPVs not available in the United States between 1997 and 2003.
