History
The origins of the LP record can be traced back to the late 1930s when researchers at the Columbia Broadcasting System (CBS) began experimenting with new recording techniques. In 1948, CBS introduced the first commercially available LP record, a 12-inch disc that rotated at 33 1/3 revolutions per minute (rpm). This new format quickly gained popularity due to its extended playing time and superior sound quality.
In the 1950s and 1960s, the LP record became the dominant format for recorded music, replacing the 78-rpm record and paving the way for the development of stereo recordings and high-fidelity audio systems. By the End of the 1960s, the LP record had become the standard format for album releases, establishing itself as an iconic symbol of the music industry and popular culture.
Despite the advent of newer technologies such as compact discs (CDs) and digital streaming, LP records have continued to maintain a devoted following among audio enthusiasts who appreciate their warm and distinctive sound characteristics.
