Sonora, a Swedish record company established on November 5th, 1932, by Erik Ljungberg, initially released reissues of German record company Artiphon due to the absence of Swedish recordings.
Sonora exclusively produced Swedish recordings, totaling around 9,000 between 1933 and 1958.
After Ljungberg's death and the cessation of shellac 78s production, Philips acquired Sonora, leading to subsequent transitions through Phonogram AB, Polygram AB, and ultimately Universal Music Group. The Sonora label's shellac releases featured various layouts and colors throughout the years.
Additionally, Sonora had branches in Norway (1934), Finland, and the USA.
