[78-L] 78rpm speed

[David Lennick]

But since the slow speed (33 1/3 RPM) was in use as early as 1926 for sync 
soundtrack discs and radio stations were playing discs of both speeds after 
1931 and 33RPM "Program Transcriptions" were marketed by RCA Victor that same 
year, the answer has to be a lot earlier, even if the general public didn't 
have reason to refer to "78s" till 1948..even then, the term "standard" 
remained popular for quite a while. The introduction of the "45" probably 
heralded the general use of speed designations. Lacquer discs, both studio and 
for home use, usually had boxes to check "78" and "33" on the labels.
