The city of Novi Sad was historically a popular place for traders. In the 19th century, it quickly became an important trading post, due to its location on the Danube river and on the natural border between the Bačka and Syrmia regions. Novi Sad is also situated in Vojvodina, Serbia, which at the time was the most developed agricultural region in the then Kingdom of Yugoslavia. It therefore became home to the country's first agricultural show in 1923, becoming international later on in 1930.

In 1958, Novi Sad Fair became a member of an international fair organization and also gained a reputation for being the most important agricultural show in the then SFR Yugoslavia. Besides organizing the annual agricultural show, the company had held many other fairs over the years, dedicated to finance, computing, banking, cars, books, pharmaceuticals, etc.
