Like many idol groups, B1A4 sought to come up with a name that was unique and catchy. In an industry where all idol group names have some sort of significance or meaning, B1A4 was no exception. It represented the members' blood types as there are four of them with type A blood and one member with type B (Ba-ro). Another meaning was that it stood for "Be The One, All For One".

The group was introduced via webtoons for their debut album which was a fusion of pop and rock. One member in particular was highlighted by the agency, the leader of the group: Jin-young. Jin-young is trained in singing, acting, and composing. In fact, the agency had announced before the group's debut that B1A4's first EP album will include a song composed and written by him.

Just two months after they finally daebuted, offers for commercials were already coming in. They decided to sign with a couple of Korean beverage companies.

Following their title track "O.K.", the guys started promoting "Only Learned Bad Things" which also garnered a positive response.
