In the presentation, he explained his strategy of separating the group into two subgroups, M1 and M2, and have them promote the same music in South Korea and China, performing the songs in both Korean and Mandarin.Lee planned to launch the group in May 2011, but their debut was delayed due to member changes and other planning. News concerning the group did not surface until October 2011, when Lee briefly discussed about the group's concept plans again in an interview withThe Chosun Ilbo. Once the members and plans were finalized, the group began to prepare for their official debut.
In December 2011, the group finalized their name to EXO, with the names EXO-K for the South Korean subgroup and EXO-M for the Chinese subgroup. Their name was taken from the word exoplanet.The twelve members were introduced individually through 23 different trailers released from December 2011 to February 2012.
