Aside from flexi-type discs such as those made in Europe around 1930 and the
various products from Flexo about the same time, the first use I know of a
plastic similar to later vinyl pressings is Vitrolac, which Victor was using
for commercial pressings in 1931. Radio transcriptions for broadcast use, the
early long-playing Program Transcriptions (only twelve-inchers used it, and
then not all of them) and some commercial 78 issues a couple of years later,
such as Schoenberg's Gurrelieder. In the late 30s, Victor was pressing Lucky
Strike premium discs on this same material. Library of Congress folk music sets
used it in 1942, as did V-Discs a year later.
