According to the commentary on the
Pioneer (GB) corporate video 1993 [11-323] , Pioneer LDCE was formed in 1991.
Early 1981 - 1982 Pioneer releases with a blue top on a white back ground eg
Laserdisc: What it is, How it works (1980) [USP-001] seem to be from Pioneer Artists, Pioneer Imports, Pioneer LDC, or perhaps, just Pioneer. Does a publisher need to be added.. simply Pioneer. Would Pioneer Electronics Corp be inputted as Pioneer LDC? Was Pioneer LDC a name Pioneer used in 1981?
Also, my UPC test disc from about 1981
UPC Test Disc B1 [GGV-091] contains footage of the disc pressing facility in Kofu, in which a machine has a sign saying Universal Pioneer. The disc itself has a Universal Pioneer label. Does this also need adding as a publisher?? I have submitted pictures of both and the insert sheet from the UPC disc.
