Changes

In 2011, SM Entertainment CEO, Lee Soo-man, revealed plans to debut a new boy group that would be divided into two sub-groups, 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 its name as EXO, taken from the word "exoplanet". The news of an upcoming debut from SM Entertainment attracted substantial media attention from within South Korea and internationally, with many comparing EXO to fellow SM boy group [[TVXQ]].
