Interesting Fact - Time

The average CD (compact disc) can hold 74 minutes’ worth of recorded sound.

(What's interesting about this is why they chose 74 minutes.  Why not 60 or 120?  Well allegedly, when CDs were developed by Philips and Sony in the 70s, one of the developers, Norio Ohga, decided that a single CD should be able to contain the longest recorded version of Beethoven’s Ninth Symphony, which is 74 minutes long.

Luckily they didn't decide on the symphony Victory at Sea, by Richard Rodgers, it is 13 hours long!)
