The mix of occupants and tenants were soon modified, with the cinemedia centre becoming the new body known as ACMI, offices for multicultural broadcaster SBS added, and the gallery space becoming the Australian art wing of the National Gallery of Victoria, which became the Ian Potter Centre. The performance arts space was dropped, the number of commercial tenancies increased, and the south end of the Atrium became an auditorium. A new substantially rearranged design incorporating the new program was revealed in late 1998.
