  There was another more mundane reason than that.
44.1kHz allowed
 engineers to store an even number of samples in either an NTSC or a
 PAL scanline when using UMatic video recorders to record digital
 audio.  Sony had supposedly even planned a line of products based on
 the idea, though they never came to market. 
In college we recorded recitals on such a system.  There was A/D box with
meters on it ("If it clips you're fired!") and a Betamax VCR.  I think it
was all Sony but I don't actually remember.
