Vinyl records were incredibly popular in the 50s, 60s, 70s, and 80s, with over 530 million records bought each year in the 70s, but they declined in popularity with the rise of cassettes and CDs, only to make a comeback in the 2000s and outsell CDs in 2020.

Edward Leon Scott de Martinville was the first person to figure out how to capture and encode sound onto a vinyl record using a vibrating tool, which is still considered a bit like black magic.
16:56
Edison and Bell both made advancements in recording sound onto vinyl records, with Edison using paraffin wax sheets and Bell using metal cylinders wrapped in aluminum foil, which eventually evolved into wax cylinders that were popular for recording and listening to music in the 19th century.
22:20
Emil Berliner invented the gramophone and shellac records, which became the standard for listening to music from the 1890s to 1950, as they were easier and cheaper to reproduce than wax cylinders.
27:56
Vinyl records, made of polyvinyl chloride (PVC), were invented in the 1930s as a solution to the fragility of shellac records, but it wasn't until after World War II that vinyl records became popular and more efforts were put into making them work.
34:50
Vinyl records allowed for the creation of stereo records, which provided a more immersive and rich listening experience by having different channels of sound coming out of separate speakers.
40:06
Vinyl records are made by etching the sound waves into a mechanical record using a cutting lathe, which is essentially a large industrial turntable.
45:56
Vinyl records are made by cutting grooves into a lacquer disc using a vibrating ruby chisel, and the grooves can stretch as long as seven football fields, with the average LP being about one and a half football fields long.
51:12
Vinyl records contain carbon black to repel dust and are better at repelling dust than clear records, and when played on a turntable, the grooves on the record are read by a sensitive needle or stylus that translates the mechanical encoding into electricity, which is then amplified and played through speakers.
56:36
Vinyl records have a warmer sound and offer a more immersive experience with album art and liner notes, while digital recordings have a wider frequency range and can reproduce sound more accurately, but the sound quality can be affected by compression and playback devices.
01:01:54
Vinyl records can be made from digital files, so the argument that vinyl is superior to digital is moot.
