WWE Brand Extension
Raw created WWE Raw Tag Team Championship, revived the United States Championship, and became the exclusive home of the Cruiserweight Championship. Meanwhile, Smackdown  became the exclusive brand for WWE's original WWE SmackDown Tag Team Championship, the Intercontinental Championship, and the Women's Championship. The end result was each brand having four championships. When ECW was revived in 2006, the ECW Championship was re-established and is that brand's world title.
