First split (2002–2011)
In its conception, according to Bruce Prichard in his Something to Wrestle podcast released in October 2018, the then World Wrestling Federation (WWF) originally planned to make SmackDown! an all-women's brand but ultimately decided against it because of the lack of talent.[2]
In March 2002, WWF underwent the "brand extension",[3] a process in which WWF divided itself into two branches with separate rosters, storylines and authority figures.[3] The two divisions, hosted by and named after Raw and SmackDown!, would compete against each other. The split resulted from WWF purchasing its two biggest competitors, World Championship Wrestling (WCW) and Extreme Championship Wrestling (ECW); and the subsequent doubling of its roster and championships. The brand extension was made public during a telecast of Raw on March 18, initiated with the first draft a week later on the March 25 episode of Raw and became official on the April 1 episode of Raw.
Wrestlers began to wrestle exclusively for their specific show. At the time, this excluded the WWF Undisputed Championship and WWF Women's Championship as those titles would be defended on both shows.[3] In August 2002, then WWE Undisputed Champion, Brock Lesnar, refused to defend the title on Raw, in effect causing his title to become exclusive to SmackDown!.[3] The following week on Raw, Raw General Manager Eric Bischoff awarded a newly instated World Heavyweight Championship to Raw's designated number one contender Triple H. Accordingly, Lesnar's championship was no longer deemed "undisputed". Following this, the WWE Women's Championship soon became a Raw exclusive as well. As a result of the brand extension, an annual "draft lottery" was instituted to exchange members of each roster and generally refresh the lineups.
SmackDown! was the home brand for many top WWE stars including Eddie Guerrero, Batista, Big Show, John "Bradshaw" Layfield (JBL), Kurt Angle, Edge, The Undertaker, Rey Mysterio, John Cena, and Torrie Wilson. Guerrero would go on to become the WWE Champion as part of the show, thus becoming the main feature of SmackDown! throughout 2004 and the most popular wrestler of that year. The biggest star of the next decade, John Cena, started his WWE career on this brand and rose to stardom as "Doctor of Thuganomics" on the show, eventually winning his first WWE Championship during his tenure on the brand.
On June 6, then WWE Champion John Cena switched brands from SmackDown! to Raw as part of the month-long 2005 draft lottery. This effectively left SmackDown! without a world title. On the June 23 episode of SmackDown!, SmackDown! General Manager Theodore Long scheduled a six-man elimination match between Booker T, Chris Benoit, Christian (replacing Big Show, who was picked by Raw in the lottery), John "Bradshaw" Layfield, Muhammad Hassan and The Undertaker to crown the first SmackDown! Champion. On the June 30 episode of SmackDown!, JBL won the match, but Long appeared afterward and stated that even though he had won the match SmackDown! did not need a championship anymore, instead revealing that JBL was the number one contender for the World Heavyweight Championship, at which point Batista, then World Heavyweight Champion, entered the ring as SmackDown!'s final draft lottery pick.
At the SmackDown! taping on January 10, 2006, that aired January 13, Batista had to forfeit the World Heavyweight Championship because of a legitimate triceps injury suffered at the hands of Mark Henry the previous week. Long decreed a battle royal for the vacant title, which was won by Kurt Angle, who was on the Raw brand, but switched to the SmackDown! brand for the duration of his reign as champion. On the April 7 episode of SmackDown! (which was taped on April 4), Long revived the King of the Ring tournament after a four-year hiatus as a SmackDown! exclusive tournament. The tournament ended at Judgment Day with Booker T as the winner, defeating Bobby Lashley in the final.
On October 16, 2007, the SmackDown! and ECW brands began a talent exchange, allowing their respective talent to appear and compete on either brand, as ECW was broadcast live from the same arena where SmackDown! was taped.[4][5]
During the 2008 WWE draft, WWE Champion Triple H was drafted to SmackDown, resulting in two world championships appearing on the brand – Edge was the World Heavyweight Champion at the time – and leaving Raw without a world title. However, Edge was attacked by Batista on the June 30 episode of Raw and immediately afterwards CM Punk cashed in his Money in the Bank contract to become World Heavyweight Champion, bringing the World Heavyweight Championship back to Raw for the first time since 2005. Also that year, for the first time in the brand's history a women's exclusive championship was introduced, the Divas Championship, a counterpart to the Women's Championship that had been the only active championship competed for by Divas, but which was exclusive to Raw, meaning that the Divas on SmackDown had no championship to compete for. Michelle McCool became the inaugural champion by defeating Natalya on July 20 at The Great American Bash.
On February 15, 2009, at No Way Out, Edge won the World Heavyweight Championship in Raw's Elimination Chamber match, thus making it a SmackDown exclusive title and giving SmackDown two top tier championships.[6] As a result of the 2009 WWE draft in April, then WWE Champion Triple H was drafted to Raw while the World Heavyweight Championship also moved to the Raw brand after Edge lost the title to Cena at WrestleMania 25, once again leaving SmackDown without a world title.[7] SmackDown regained the World Heavyweight Championship at Backlash when Edge invoked his WrestleMania rematch clause and defeated Cena in a Last Man Standing match to win the championship back.[8] In addition, Raw and SmackDown exchanged both women-exclusive championships with Raw gaining the Divas Championship and SmackDown gaining the Women's Championship. This marked the first time in history that the Women's Championship had ever been exclusive to SmackDown. Raw and SmackDown also exchanged the United States Championship (which became exclusive to Raw) and the Intercontinental Championship (subsequently exclusive to SmackDown) for the first time since August 25, 2002.[7]
On the August 29, 2011, episode of Raw, it was announced that performers from Raw and SmackDown were no longer exclusive to their respective brand.[9] Subsequently, championships previously exclusive to one show or the other were available for wrestlers from any show to compete for—this would mark the end of the brand extension as all programming and live events featured the full WWE roster.[10] In a 2013 interview with Advertising Age, Stephanie McMahon explained that WWE's decision to end the brand extension was due to wanting their content to flow across television and online platforms.[11]
