History of the CD. Exactly 25 years ago the world's first compact disc was produced at a Philips factory in Germany, sparking a global music revolution. More than 200 billion CDs have been sold worldwide since then and it remains the dominant format despite the growth in digital downloads. The CD was jointly developed by Philips and Sony and the disc has also become a key storage method for computer users. The first CD produced was The Visitors by Abba. Piet Kramer, who was a member of the optical group at Philips during the disc's development, said: When Philips teamed up with Sony to develop the CD, our first target was to win over the world for the CD.
