From The Mathematical Theory of Communication by Claude Shannon (1948):

The choice of a logarithmic base corresponds to the choice of a unit
for measuring information. If the base 2 is used the resulting units
may be called binary digits, or more briefly bits, a word suggested by
J. W. Tukey.

There it is, folks. Straight from the horse's mouth. ...RM
