Formed under MBK Entertainment, DIA consists of members SeungHee, Eunice, Cathy, Jenny, ChaeYeon, EunJin and YeBin. MBK had originally planned on debuting the group under a survival program show, so that the public could get to know the potential members before debut.
However, MBK had scrapped the show idea and decided to debut the group with 7 members. The group of 7 had debuted on September 14, 2015 with their first debut album “Do It Amazing (DIA)”.
After their first promotions, the group under went minor line-up changes. Cathy and ChaeYeon had gone on a hiatus after signing to participate in “Produce 101”. Although ChaeYeon had debuted as I.O.I through the program, MBK had announced that ChaeYeon will promote as a DIA member as well.
