"the exact sampling rate of 44.1 kHz was inherited from a method of converting digital audio into an analog video signal for storage on U-matic video tape, which was the most affordable way to transfer data from the recording studio to the CD manufacturer at the time the CD specification was being developed."

So again this has absolutely nothing to do with 'the limits of human hearing'.

That is fairly selective quoting. A few linea up, that wikipedia article states:

The selection of the sample rate was based primarily on the need to reproduce the audible frequency range of 20 Hz - 20 kHz.

So, 44100 Hz is both 'around 40kHz' and 'a fixed number of samples per PAL scan line'. That is similar to how the first Mac got 22kHz sampling (http://www.folklore.org/StoryView.py?project=Macintosh&s...)
