WE 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. In 2022, the company began recognizing Money in the Bank as one of their five biggest events of the year, thus making it a "Big Five" event along with the classic "Big Four"; King of the Ring was also considered a "Big Five" event from 1993 until 2002, after which, it was discontinued as a PPV.
