I want to know the answer to the following question:
Who was the head of CBS at the time?
All the background I'm provided with is that "Wallerstein, who was promoted at the end of 1947 from president to chairman of the record company, restored Columbia's status as a leading record company and spearheaded the successful introduction of the long playing (LP) record before he retired as Columbia's chairman in 1951.". Is that enough to answer the question?
