At WWE's The Bash on June 28, 2009, Chris Jericho and his partner Edge, both heels, won the Unified WWE Tag Team Championship as surprise entrants in a tag team match. When Edge suffered a torn Achilles tendon shortly thereafter which left him unable to wrestle, Jericho exploited a contractual loophole that allowed him to choose a new partner to replace Edge so that Jericho's reign could continue uninterrupted, while insulting Edge for being injury prone.
On July 26 at Night of Champions, Jericho revealed fellow heel Big Show as his new tag team partner, and they defeated Legacy members Cody Rhodes and Ted DiBiase to retain the Unified WWE Tag Team Championship, thus allowing Show (who was from the Raw brand) and Jericho (who was from the SmackDown brand) to appear on both brands. Jeri-Show would then feud with Cryme Tyme (JTG and Shad Gaspard), which culminated in a successful title defense for Jeri-Show at SummerSlam on August 23. Jericho and Show would then feud with Montel Vontavious Porter and Mark Henry, which would also result in another successful title defense for Jeri-Show at Breaking Point on September 13 against them. Next, Jeri-Show would move on to feud with Batista, who then challenged for the Unified WWE Tag Team Championship with Jericho's rival Rey Mysterio at Hell in a Cell on October 4, where resulted in another successful title defense.
On the October 5 episode of Raw, Jeri-Show would begin a feud with Shawn Michaels and Triple H of D-Generation X (DX) following a loss in a non-title match. Leading up to Bragging Rights, Jericho was named as a co-captain (with Kane) for Team SmackDown while Show joined Team Raw, which was captained by DX. At Bragging Rights on October 25, Show turned on Team Raw when he attacked his teammates Kofi Kingston and Triple H, resulting in Jericho getting the win for Team SmackDown. Show would then reveal that his motives for aiding Team SmackDown was so that he would be granted a shot against SmackDown's World Heavyweight Champion The Undertaker, while Jericho would insert himself into the title match as well after defeating Kane, thus making it a triple threat match. At Survivor Series on November 22, The Undertaker retained his World Heavyweight Championship after Jericho and Show turned on each other despite working together throughout most of the match. Jeri-Show would then continue their feud with DX and on December 13 at TLC: Tables, Ladders & Chairs, they lost the Unified WWE Tag Team Championship to DX in a Tables, Ladders and Chairs match, ending their reign at 140 days. On the December 14 episode of Raw, Jeri-Show won a Slammy Award for "Tag Team of the Year", while that same night they used their rematch clause against DX, who quickly intentionally disqualified themselves and retained Unified WWE Tag Team Championship (as a result, Jericho, from the SmackDown brand, could not appear on Raw as he was no longer a Unified WWE Tag Team Champion). DX granted Jeri-Show yet another rematch for the Unified WWE Tag Team Championship, with the additional stipulation that Jericho had to "leave Raw forever" if Jeri-Show lost, which they did on the January 4, 2010 episode of Raw, marking the end of Jeri-Show.
After their breakup, Edge made his return at the 2010 Royal Rumble match to feud with Jericho, eliminating Jericho en route to winning the Rumble. Meanwhile, Show would go on to win the Unified WWE Tag Team Championship back from DX when he teamed with The Miz, forming ShoMiz. Jericho would eventually return to Raw again when he was drafted to the Raw brand through the 2010 WWE draft.
On the July 9, 2012 episode of Raw, Jeri-Show reunited for one-time to take on John Cena and Kane in a tag team match, which they lost by disqualification.
On the September 5, 2014 episode of SmackDown, Jeri-Show had a one-night reunion, competing in a ten-man tag team match that consisted of themselves teaming with John Cena, Mark Henry and Roman Reigns against Kane, Seth Rollins and The Wyatt Family (Bray Wyatt, Erick Rowan and Luke Harper), which Jeri-Show's team won by disqualification after The Wyatt Family broke up Cena's STF on Rollins and refused to stop their assault on Cena.
On the January 28, 2016 episode of SmackDown, Show helped Jericho, Reigns and Dean Ambrose from a Wyatt Family assault, having a one night reunion for Jeri-Show.
