These discs were initially made of glass and were later switched to zinc and eventually plastic.

About ten years later in 1887, Emile Berliner improved upon the technology by creating recordings on flat discs, using his patented gramophone. The cylinder used to record this at the time was large and inefficient. With his first model ready to launch, he recorded himself, saying, “Mary had a little lamb.” Thus, these were the first words ever recorded on the phonograph.

Their precursor was the phonograph, invented by Thomas Edison in 1877.

But the question remains: What is the difference between these speeds? And why were they chosen in the first place? To answer these questions, we’ll have to take a little dive into history. Most high-quality lp players & record players will come equipped to turn at these three standard speeds. These numbers refer to the rate at which the record spins on the record player, measured in revolutions per minute (rpm). One, in particular, has to do with three numbers: 33, 45, and 78. Now, as record sales are skyrocketing, the age-old questions are resurfacing. And before vinyl, there were only shellac records. LPs, for example, didn’t enter the lexicon until 1948. These are all words that describe the same thing.
