At first, Sonora didn't have any Swedish recordings to release so their initial releases were reissues of the German record company [url=http://www.discogs.com/label/Artiphon]Artiphon[/url]. From 1933 and forward, Sonora solely released Swedish recordings. Between 1933 and 1958 Sonora made approximately 9,000 recordings.

When the founder Erik Ljungberg died and the production of shellac 78s ceased, Sonora was purchased by Philips and became which later turned to and then [url=http://www.discogs.com/label/PolyGram]Polygram AB[/url] and now Universal Music Group.
