44100 has more smaller-number integer factors (80; original research) than 48000 (63), the 'pro audio sampling rate'. According to this guy (who may be a master FAQ collector, see [https://stason.org/ https://stason.org/]): "It turned out that both NTSC and PAL formats (the video standards used in US/Japan and Europe, respectively) could handle a rate of 44100 samples per second. This rate was carried over into the definition of the compact disc. The sampling rate for "professional" audio, 48KHz, was chosen because it's an easy multiple of frequencies used for other common formats, e.g. 8KHz for telephones. It also happens to be fairly difficult to do a good conversion from 48KHz to 44.1KHz, which makes it harder to, say, copy an audio CD with a "consumer" DAT deck."
