From sometime in the forties onward, major record companies pressed their
product in vinyl as well as shellac. These discs were comparatively noiseless
(although they had a short useful lifespan, due to the tracking pressures
of the era) and were thus used as "demonstration samples" or distributed
for airplay. In fact, vinyl records first appeared as a substitute for
(then unavailable) shellac discs...and were thereafter offered as an
"on-request" option for radio stations who needed "promo discs."
