The aim of this essay is to show how, from the 1950s to early 1970s, arts and technologies evolved side by side owing to the new practices borrowed from the legacy of abstract art. Both in Italy and Croatia, several left-wing scholars wrote on the relations between art and technology as an important factor of social progress. On this basis, it was implied that the leftist ideology had a decisive effect on the new artistic attitudes. These took place in Zagreb during the Nove tendencije exhibitions, held in 1961 and 1963 respectively, where several kinetic and so-called "programmed" artworks were displayed. However, just after the 1965 edition of Nove tendencije, Italian artistic research was changed by the Arte Povera movement in 1967. As a consequence, the gap between "programmed" art the Left increased. Although in Italy such changeover caused a complete break in the relationship between art and technology, in Zagreb the last Tendencije exhibitions, held in 1969 and 1973 respectively, combined the computer-based and conceptual art trends with left-wing radicalism
