Original: After three years on the SmackDown brand, the WWE Championship switched brands during the 2005 WWE Draft Lottery, in which the WWE Champion John Cena was drafted to Raw while the World Heavyweight Champion Batista was drafted to SmackDown.
Simplified: brand from August 26 2002 until June 6 2005, when the WWE Champion, John Cena, was drafted to the RAW brand during the 2005 WWE Draft Lottery. This left the RAW brand with the two top titles in WWE until the World Heavyweight Champion, Batista, was drafted to the SmackDown!
