Established in 1992, UMco originally engaged in the sale of textiles, but since 1997 it has expanded its activities into printing and publishing. UMco was the first company in Slovenia to distribute free promotional postcards (named Felix). Today they are used widely for promoting cultural events at over 300 locations (restaurants, cinemas, clubs) around the country.

In 2000 UMco started to publish and distribute the free film and popular culture magazine e-Premiera. A year later its publishing department was established, and by 2005 more than 50 books had been issued in the so-called Premiera Book Collection, which comprised theoretical works (Blue Premiera), more popular themes (Red Premiera), scripts (Green Premiera), special publications (Mini Premiera) and books on art disciplines other than film (White Premiera). In 2005 UMco launched Bukla, a magazine on new books and multimedia, which is also available free of charge at cultural venues.
