ATBO (Korean: 에이티비오; Japanese: エイティビオ) is a seven-member boy group under IST Entertainment, created from the survival show called THE ORIGIN – A, B, OR What?. They later made their debut on July 27, 2022, with the release of their mini album "The Beginning : 開花".
The name of the group, "ATBO", stands for At The Beginning of Originality. Initially, the group was supposed to be named "ABO", but it was changed due to concerns raised by fans, as "ABO" was considered a racial slur in some regions, which prompted the name change to "ATBO".
