The new LP was considered a huge leap forward for listening to pre-recorded Classical music. A pop song took, on average, two or three minutes to play, which was just perfect for a 10 or 12 inch 78 rpm record. A symphony required up to 5 or 6 records on 78 rpm and had to be changed 10 to 12 times with the music often interrupted in the middle of a musical phrase. There were automatic 78 rpm record changers, but they were clunky and could damage your records. You also had to account for the amount of storage space needed for the brittle, breakable shellac 78s. The most dramatic part of Goldmark’s demonstration was when he was photographed holding a few dozen LPs while the equivalent in 78s were stacked six feet high next to him.
The introduction of the LP was not without controversy. Columbia’s great rival RCA Victor was developing its own system of 7” short playing vinyl records that played at 45 rpm. RCA engineers insisted that quality control problems with LPs would doom it. This started what was to be known as “The War of the Speeds” in which both companies spent a ton of money on print ads to woo the public before RCA conceded and converted to LP. When it was settled, it set up the paradigm that lasted for nearly 40 years: LP for albums, 45s for pop singles.
