CD Origins Revealed

The standardization of compact discs hinged on the debate over their size, ultimately settling on a diameter that could accommodate Beethoven's 9th Symphony. Interestingly, the decision to ensure the entire symphony fit on a single disc is attributed to the wife of Sony's CEO, although this story has faced skepticism over the years. Despite the CD's capacity for 74 minutes of music, a full version of the symphony wasn't released until 1997, making the experience of listening to it—especially live—truly unforgettable.
