On October 17, 2007, SmackDown! and ECW announced a talent sharing agreement that made it where talent from either brand's roster can compete on both brands. As a result, the title was fought for on both brands. In late 2008 through early 2009, WWE Tag Team Champions The Colóns (Carlito and Primo) engaged in rivalry with the World Tag Team Champions John Morrison and The Miz, which resulted in the announcement on the March 17 edition of "ECW" that at WrestleMania XXV both teams would fight for their titles against each other and the winning team would hold both titles.
