CDs were designed to play 72 minutes of music because that's the length of Beethoven's Ninth Symphony.

Infact verdict: Mixed (50/100).

The claim that CDs were designed to play 72 minutes of music to accommodate Beethoven's Ninth Symphony is a well-known anecdote. However, there is no external evidence found to verify this claim. It is often cited in discussions about the development of CDs, but without concrete evidence, it remains a popular story rather than a verified fact. Therefore, the claim is treated as a historical anecdote rather than a factual statement.
