2011: Formation
In May 2011, at a Hallyu business seminar held at Stanford University, Lee Soo-man spoke about a strategy of debuting a new boyband, in which they would be divided into two subgroups, promoting the same music simultaneously in South Korea and China by performing songs in both Korean and Mandarin. After several member changes, in December 2011, the group finalized their name to Exo, taken from the word exoplanet. They are divided into two subgroups, Exo-K ('K' for Korean) for South Korea and Exo-M ('M' for Mandarin) for China. They debuted their first televised performance at SBS's annual Gayo Daejun event on December 29, 2011.

2012: Debut and Mama
Exo-K and Exo-M's prologue single "What Is Love" was released on January 30, 2012, in mainland China and South Korea. The single peaked at number 88 on South Korea's Gaon Single Chart. On March 9, the group released their second prologue single "History", which was written and produced by Thomas Troelsen and Remee. The single peaked at number 68 on the Gaon Single Chart and number six on China's Sina Music Chart.

A concert for the group was held in Seoul's Olympic Stadium on March 31. Approximately 3,000 fans from 8,000 applicants were selected to attend. A second concert was held in the Great Hall of the Beijing University of International Business and Economics on April 1.

On April 8, Exo-K performed on South Korea's music program The Music Trend, while Exo-M made their debut in China's Top Chinese Music Awards on the same day. The mandarin version of Mama reached number two on China's Sina Album Chart, while the Korean album peaked at number one on the Gaon Album Chart and number eight on the Billboard World Albums Chart. The mandarin version of "Mama" music video reached number one on Chinese streaming websites, while the Korean version reached number seven on YouTube's Global Chart.

2013: XOXO, Commercial success and Miracles in December
The group's first studio album, XOXO was released on June 3, 2013 with two versions, a Korean-language and a Mandarin-language edition. Unlike Mama era when Exo-K and Exo-M had separate promotions, XOXO was jointly promoted; mainly in South Korea. Exo recorded together for the album's lead single, "Wolf", but the rest of the album tracks were recorded separately. The two versions collectively peaked at number one on the Billboard World Album Chart a week after release.

A repackaged version of XOXO, titled Growl, was released on August 5, 2013 with three additional tracks. The reissue's lead single, "Growl", was released on August 1, 2013. "Growl" peaked at number three on Billboard's Korea K-Pop Hot 100 and number two on the Gaon's Singles chart. As of December 2013, all versions of XOXO have collectively sold over one million copies, making Exo the first Korean artist to sell over a million copies of one album in twelve years and breaking the record for being the fastest-selling K-pop act. XOXO was named Album of the Year at the 2013 Mnet Asian Music Awards. XOXO is the best selling album in South Korea of 2013, winning the Disc Daesang Award at various award ceremonies like the Golden Disc Awards.

Exo's second EP Miracles in December was officially released on December 9, 2013 as a special winter album through South Korean commercial outlets and online music stores. Exo jump-started album promotions through their reality show Exo's Showtime, which premiered on November 28, 2013 on the cable channel MBC Every 1.

2014: Overdose, Kris' and Luhan's lawsuits and first solo concert
Exo's third EP, Overdose, was released on May 7, 2014. Originally scheduled to be released on April 21, the album was delayed due to the Sewol Ferry Accident on April 16. Overdose was promoted similarly to Mama, with Exo-M promoting primarily in China and Exo-K in South Korea. The album reached over 660,000 preorders before its release, making it the most pre-ordered Korean mini-album in history. The Korean edition also peaked at number two on Billboard's World Albums Chart, and number 129 on the Billboard 200, making Exo the highest charting Korean male group act on the Billboard 200 at the time. Overdose became the best selling album in South Korea of 2014 and was the first mini album to top the yearly charts and win the Album of the Year Award at Mnet Asian Music Awards. By the end of 2014, Exo was Japan's best-selling K-pop artist of the year.

On May 15, 2014, S.M. Entertainment confirmed that Exo-M's leader, Kris, had filed a lawsuit against the agency to terminate his contract, stating violation of human rights as the main reason. On October 10, Exo-M's Luhan also filed a lawsuit against S.M. Entertainment to nullify his contract, because of health issues and being treated differently than the Korean members, therefore having no promotions.

S.M. Entertainment announced that Exo would continue to promote with 10 members. The group held their first solo concert "Exo from Exoplanet ＃1 - The Lost Planet" starting May 24 at the Seoul Olympic Gymnasium. Tickets for the concert sold out in 1.47 seconds, breaking the record for the fastest sold out concert by a Korean artist.

2015: Exodus, Tao's lawsuit, Japanese debut and Sing for You
Exo's second solo concert was announced in January 2015 entitled Exo Planet ＃2 - The Exo'luxion. Five concerts were held in Seoul at the Olympic Park Stadium starting March 7. 1.2 million fans had attempted to buy tickets online. On February 4, 2015, S.M.

The lawsuit was to stop their acting and advertisement under the use of the S.M. trademark.

Exo's second studio album, Exodus, was released on March 30, 2015 in both Korean and Mandarin versions.

The title track, "Call Me Baby", was released early on March 27, due to leaked versions of the song. The music videos were released four days later, with the Korean version later becoming the most watched K-pop music video in the first half of 2015. Exo also starred in their own mini drama series titled Exo Next Door, which became the most watched Korean web drama in 2015 until later being surpassed by member Xiumin's web drama, Falling for Challenge. "Call Me Baby" proved to be successful, winning eighteen times on music shows, making it the second most awarded song of all times. The album's Korean version also broke records after staying at number one on the album chart for four consecutive weeks. Exodus eventually went on to sell over a million copies, and is the group's second album after XOXO to do so. It was named Album of the Year at the 2015 Mnet Asian Music Awards, making this the third consecutive win in this category for the group since 2013. In May, Exo broke the record on Billboard as the highest ranking Korean artist, topping at 90th place. Exo also entered the Canadian Billboard Hot 100 chart at number 98, making them the first K-pop group and second Korean artist to enter the Canadian chart.

On April 22, member Tao's father posted a letter through Weibo expressing his sentiments for his son to withdraw from the group and return to China; due to lack of support concerning individual career developments and health issues. Tao had previously sustained several injuries which had not been properly treated that worsened and caused him to be absent during promotions for the group's second studio album Exodus. On April 23, S.M. Entertainment released an official statement saying that they would be "seeking a solution in a developmental direction" by negotiating with Tao and his father. Tao later confirmed that he had left S.M. Entertainment and after failed negotiations, Tao filed an official lawsuit against S.M. Entertainment on August 24 for the termination of his exclusive contract.

On June 3, a repackaged version of Exodus, titled Love Me Right, was released. This edition contains the original tracks from Exodus and four new songs, including the title track "Love Me Right".
