In the late 1970s the Second Century Society and the Print and Drawing Society were both formed. The Second Century Society, later known as the IMA Council, was founded to celebrate donations of $1,000 or more to the museum's annual operating fund, attracting more than 200 contributors during its inaugural year.[5] In 1979, the Print and Drawing Society exhibited 70 artworks spanning 500 years in their first exhibit, The Print and Drawing Society Collections.[136] By the late 1980s the museum had expanded its affiliate program to include the Decorative Arts Society, the Asian Arts Society,[55] the Ethnographic Arts Society, and the Fashion Arts Society.[137]
