In October 2007, SmackDown and ECW began a talent exchange agreement, which meant that SmackDown wrestlers could appear on ECW and vice versa. This allowed the United States Championship and WWE Tag Team Championship to be shared between the two brands. In July 2008, the WWE Divas Championship was created for SmackDown, allowing SmackDown's women wrestlers to compete for a title. A talent exchange between ECW and Raw then began in September 2008. After John Morrison and The Miz of ECW became World Tag Team Champions, they appeared more frequently on the Raw brand, moving to a feud with reigning WWE Tag Team Champions of SmackDown, brothers Carlito and Primo Colon. The teams fought several non-title and title bouts for their respective brands' tag team championships before the two fought in a winner-take-all title unification lumberjack match at WrestleMania XXV. Carlito and Primo would go on to win the contest, forming the Unified WWE Tag Team Championship. The tag team championships remained separate titles, but were defended collectively as the Unified WWE Tag Team Championship until the then-anonymous general manager of Raw announced that the World Tag Team Championship would be retired in favor of continuing the WWE Tag Team Championship, which received a new, single set of belts. On February 16, 2010, the ECW Championship was deactivated along with the ECW brand. On September 19, 2010, at Night of Champions, the Women's Championship was unified with the Divas Championship, retiring the Women's Championship in the process; the Divas Championship was briefly referred to as the Unified WWE Divas Championship. The first brand extension would then end a year later and all champions could appear on both shows.
