Fadlan soo koob nooca duubista ee Spalding uu sameeyay sanad walba.
Context:Intii lagu jiray xilligii 78, markii awoodda ugu badan ee hal dhinac oo caadi ah ama silsilad caadi ah ay ka yar tahay shan daqiiqo, Spalding wuxuu si ballaaran ugu duubay Edison Records, oo leh dhowr arrimood oo ku saabsan silsiladaha iyo kuwo kale oo badan oo ku saabsan cajaladaha dheeman. Intooda badani waxay soo bandhigeen shaqooyin gaagaaban ama qaybo dheeri ah oo ku habboon hal dhinac oo rikoodh ah. Diiwaanadaas oo dhan waxaa lagu sameeyay habka maqalka, iyo sidoo kale si toos ah loo jaray, illaa 1925, laakiin wuxuu sameeyay duubistiisii ugu horreysay ee korantada 1926 ee Brunswick Records isagoo adeegsanaya nidaamka "Light-Ray" ee dhibaatada leh ee shirkadda. Kadib khibradiisa aan ku qanacsanayn ee Brunswick, Spalding wuxuu ku laabtay Edison wuxuuna sameeyay qaar ka mid ah Edison korantada hill-and-dale Diamond Discs iyo sidoo kale dhowr Edison "Needle Cut" duubista dhinaca dabayaaqadii 1928. Kuwani waxay ahaayeen kuwo sifiican loo duubay marka loo eego Spalding's Brunswicks, laakiin Diyamantiyada Diyamantigu waxay iibiyeen wax yar sida badeecadaha kale ee Edison ee xilligaas, iyo "Needle-Cut" discs ayaa la soo saaray oo keliya muddo aad u gaaban - laga bilaabo Ogosto ilaa Nofeembar 1929 - waana dhif iyo naadir maanta. Kadib burburkii shirkadda Edison bishii Nofeembar 1929, wuxuu u duubay RCA Victor Records dhowr shaqooyin oo dheeri ah oo lagu jabiyay dhinacyo badan.
