[1][2] The Biennial of Industrial Design (Slovene: Bienale industrijskega oblikovanja) was officially founded in the autumn of 1963 at the initiative of the Ljubljana City Council, the Chamber of Commerce of the Socialist Republic of Slovenia, and various professional associations.
The exhibition was conceived as a biennial forum to compare Yugoslav and foreign achievements in industry.
In addition to the Triennale di Milano, BIO was one of the most important European design events in the 1960s, and the first biennial of its kind in the world.
[3][citation needed] The purpose of the Biennale was to promote and facilitate the development of Yugoslav industrial production, to influence the exchange of well-designed industrial objects on national and international markets, and to raise the general level of design apperception and good taste through educational and information campaigns.
For more than forty years, BIO exhibitions followed the same concept created for the first Biennial in 1964 (BIO 1), when objects were organized according to the following categories: furniture, lamps, textiles, hospitality, household appliances and appliances, optical objects, electrical engineering, machinery and telecommunications equipment, machinery, industrial products from the mechanical engineering industry, sports equipment, toys, architectural details, transport, packaging, and visual Communication.
