"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 CD's have been sold since 17 August 1982.

Abba had the first CD to0 be produced (The Visitors).

Piet Kramer, who was a member of the optical group at Philips during the disc's development, told the BBC "When Philips teamed up with Sony to develop the CD, our first target was to win over the world for the CD. We did this by collaborating openly to agree on a new standard. For Philips, this open innovation was a new approach and it paid off."
