B1A4 (Korean: 비원에이포) is a South Korean boy band formed by WM Entertainment. The group debuted on April 23, 2011 with the single "O.K" from the EP Let's Fly, after being introduced to the public through a webtoon. They have released nine studio albums (four Korean and five Japanese) and seven EPs, as well as four compilation albums. The group had considerable commercial and critical success in both the Korean and Japanese markets. They have also toured in the United States. The group has been dubbed "countryside-dols" (countryside idols) by the Korean media due to the fact that all of the members of B1A4 are from the countryside: Jinyoung is from Chungju, North Chungcheong Province; CNU from Cheongju, North Chungcheong Province; Sandeul from Busan; Baro from Gwangju, South Jeolla Province; and Gongchan from Suncheon, South Jeolla Province. They were also referred to as "blood-dols" (blood idols) in reference to the origins of their name (which references the group members' blood types), as well as "paper-dols" (paper idols) because of the paper classification A4. In an effort to distinguish themselves, B1A4 had also promoted a nickname "saessakdol" (새싹돌, "sprout-dol") and created a so-called "saessakchum" (새싹춤, "sprout dance"), which was showcased in various shows including Quiz to Change the World.
