Tip - History of the CD Player

       The first CD player in the world was known as the CDP-101, and it was introduced in the market by electronics giant Sony, in the year 1982. It was Nobuyuki Idei, who was the chairman and CEO of the company, who had come up with the name CDP-101, because in binary numbers 0101 stands for the number 5. It is said that Idei wanted to imply that a CD player was not of the best possible quality, but a medium one.
