Восемьдесят!
RCA Victor introduced an early version of a long-playing record for home use in September 1931. These "Program Transcription" discs, as Victor called them, played at 33⅓ rpm and used a somewhat finer and more closely spaced groove than typical 78s. They were to be played with a special "Chromium Orange" chrome-plated steel needle.
