The stereo, or stereophonic sound, was developed in the early 20th century, with key advancements made in various countries, particularly the United States and the United Kingdom. The concept of two-channel audio to create a sense of space and dimension in sound was pioneered by American inventor Alan Blumlein in the 1930s. His innovations laid the groundwork for modern stereo sound systems.
