It is said that the length of music that may be recorded on a standard CD was chosen to be 74 minutes, as that is just long enough to record a complete performance of Beethoven's Ninth Symphony.
When Philips and Sony collaborated on developing CD technology, the prototype from Philips ran for 60 minutes, but it is said that Norio Ohga, the president of Sony, insisted that 60 minutes was too restrictive and it should be 74 minutes.
Some accounts say this was because Ohga himself demanded that Beethoven's Ninth should be available on a single disc, others suggest that it was the favourite music of the wife of Sony chairman Akio Morita, while a third explanation is that the insistence came from Herbert von Karayan, conductor of the Berlin Philharmonic.
None of these explanations has been confirmed officially.
