Hi, Ken,
One space has traditionally been used in typography for a couple
reasons, not the least of which was that putting two spaces between
sentences tended to overly widen the space between sentences after
text justification (sometimes referenced as "rivers of white").
Typewriters used mono-spaced fonts and their printed output was
seldom right-left justified, so typists were told to put two spaces
between sentences to better signal the end of the sentence.
PCs, of course, originally hard-wired the keyboard to pixel
combinations that represented characters and displayed these on 80
column wide displays. These were also mono-spaced "fonts", so the PC
tradition carried over from the typewriter.
Macs, on the other hand, have always drawn their characters on the
display from a selected (typically proportional) font, so from their
beginning their displays more closely matched typography than typing.
That's why style rules typically prohibit two spaces between
sentences on the Mac. That's a general rule today, even on the modern
PC, which after a few model generations of UGLY displays, finally
followed the Mac and produced font based characters.
Interestingly, all of this tends to be moot for text typed into an
HTML page, since the browsers reduce any amount of white space to a
single character between words of text. Once again, the browsers are
following the typesetting rather than the typing tradition.
For more information without having to buy Robin Williams' book, see:

In particular, search the article for the word "wedges" for an
interesting side note on how lines of type were mechanically
justified on a Linotype machine and ended up setting the typographic
standard.
Regards,
Jerry
