  We present the culmination of our near-infrared survey of the optically
spectroscopically identified white dwarf stars from the McCook & Sion catalog,
conducted using photometric data from the Two Micron All Sky Survey final All
Sky Data Release. The color-selection technique, which identifies candidate
binaries containing a white dwarf and a low mass stellar (or sub-stellar)
companion via their distinctive locus in the near-infrared color-color diagram,
is demonstrated to be simple to apply and to yield candidates with a high rate
of subsequent confirmation. We recover 105 confirmed binaries, and identify 28
firm candidates (20 of which are new to this work) and 21 tentative candidates
(17 of which are new to this work) from the 2MASS data. Only a small number of
candidates from our survey have likely companion spectral types later than M5,
none of which is an obvious L type (i.e., potential brown dwarf) companion.
Only one previously known WD + brown dwarf binary is detected. This result is
discussed in the context of the 2MASS detection limits, as well as other recent
observational surveys that suggest a very low rate of formation (or survival)
for binary stars with extreme mass ratios.
