The studio underwent several name changes throughout the 20th century, being Soyuzkinochronika from its founding year to 1931, All-Union Newsreel Factory from 1931 to 1936, the Moscow Newsreel Studio from 1936 to 1940, the Central Newsreel Studio from 1940 to 1944, the Central Studio for Documentary Films from 1944 to 1993, and lastly its current name since the latter year. During the 21st century, the studio was on the verge of bankruptcy before liquidating in 2015.
