I want to know the answer to the following question:
What year was the Victrolac compound released?
All the background I'm provided with is that "When it came to ordinary 78 rpm records, however, the much higher cost of the raw material, as well as its vulnerability to the heavy pickups and crudely mass-produced steel needles still commonly used in home record players, made its general substitution for shellac impractical at that time.". Is that enough to answer the question?
Answer: no
