Jugoton was founded on 10 July 1947 in Zagreb, Croatia (then Yugoslavia) when the record label Elektroton was nationalised.
History It started pressing microgroove records in 1957, and in 1961 first stereo records were produced. On 11 September 1963 the new, bigger factory was opened to meet the demands of the growing market, and production numbers soon went up to 30.000 records a day. In 1971 cassette production started, and by 1982 daily production raised to 20.000 copies. Although maintaning a frequent production of licensed releases, Jugoton lowered the number of foreign artists' releases in favor of Yugoslav authors as the years have passed, and had eight different editorial boards with numerous expert collaborators. The most known programme departments were Fonoars, Discothalia and Fonolingua. At its peak, Jugoton was the largest record label, pressing plant and chain record store in Yugoslavia, and it's notable for releasing some of the most important former Yugoslav pop and rock records. After the dissolution of Yugoslavia in 1991, Jugoton changed its name to Croatia Records.
Service pressing catalog numbers As Jugoton had the largest pressing capacities in Yugoslavia, starting from early 1970s many smaller major labels (such as Suzy, Beograd Disk/Jugodisk, RTV Ljubljana/ZKP RTVL, etc.), various cultural, religious and state organizations and companies, as well as independent labels and individuals (starting from mid/late 1980s), had their records pressed at Jugoton's facilities. These numbers started with the following combination of letters (there's likely more out there): UCA-#, UCAY-# UEP-#, ULP-#, ULS-#, USD-#, UMC-#, USP-#, ULPS-#, ULPV-#, ULPVS-# (often without hyphen, or hyphen inserted after "U"). "U" stands for "uslužni" (service), and the following letters usually denote the format - EP, LP, single, cassette. From 1989 to 1991, when Jugoton had their own catalog numbers changed from LSY-##### to a longer format (which largely corresponded to the barcode which was introduced at the same time), the service pressing catalog numbers were changed as well. The format of these was U ##### E (EPs), U ##### L (LPs), U ##### S (singles) and U ##### C (cassettes). This format was retained when Jugoton changed its name to Croatia Records, which continued to press vinyl records (mostly small-run promos and service pressings) until the very end of 1994. These markings, regardless of formatting, are found in the matrix and on center labels, often backed with text "Proizvedeno u Jugotonu", "Prešano u Jugotonu" or "Tehnička usluga - Jugoton Zagreb". Additionally, the "U"-numbers were sometimes used even on Jugoton's own releases, but these are always branded with their logo on labels and/or sleeve, so any other company mentioned on these releases should be entered as an additional label.
