Why is it said that the introduction of the gramophone record changed the history of audio recording?

          One of the most successful devices that initiated a technical development was the gramophone disc. Its invention is credited to Emile Berliner.

          By the end of World War I, discs became an important commercial recording format.

         In terms of speed of the discs, there was no universally accepted standard. For a few decades, the double-sided 78 rpm disc was the standard consumer music format.

          By 1948, the Columbia Records introduced the long-playing 33 1/3 rpm vinyl record, or ‘LP’. The advantage of vinyl discs were that they showed improved performance, and were long-lasting, although more expensive.

          By the 1970s, it paved way for the introduction of electrical recording, which was the most important milestone in the history of sound recording.
