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.
Baro, the rapper of the group, was scouted by a company representative who came across his photo posted on his friend's homepage on the social network Cyworld. At his audition, Baro sang Sumi Jo's "Once I Leave" and Sung Si-kyung's "The Road to Me", as well as rapping and beatboxing. The group's leader Jinyoung was similarly discovered from a photo posted on Cyworld. He received training in composition, singing, and acting. Gongchan was also discovered on Cyworld as a result of his winning an "Ulzzang Challenge" when he was in middle school.

On April 11, the members of B1A4 were introduced through a webtoon. Initially, it was believed that B1A4 would be a mixed gender group due to the presence of a female character named Anna in the webtoon. The same day, WM Entertainment revealed a photo of the first member of the group, leader Jinyoung. The remaining members Baro, Gongchan, Sandeul, and CNU were revealed on a daily basis between April 12–15. A music video teaser for B1A4's promotional single "O.K" was uploaded on April 19.
