The compact disc is a miracle of modern technology. Your CD is read by the laser beam and makes over 44,000 arithmetical calculations every second in at least two dimensions. In 1979, the first prototype CD was revealed to technology enthusiasts in Europe and Japan. A year later, electronics companies Philips and Sony teamed up to begin working on CDs for the public.
At a time before before online music existed, it became the most sophisticated way to store and play music. On the 25th anniversary of its first public release in 1982, it was estimated that 200 billion CDs had been sold worldwide. Despite costing up to $1,000, over 400,000 CD players were sold in the United States between 1983 and 1984.
As a reminder, CD Player Day is celebrated on October 1st.
