  Microlensing is potentially sensitive to multiple-planet systems containing
analogs of all the solar system planets except Mercury, as well as to free
floating planets. I review the landscape of microlensing planet searches,
beginning with an outline of the method itself, and continuing with an overview
of the results that have been obtained to date. Four planets have been detected
with microlensing. I discuss what these detections have taught us about the
frequency of terrestrial and giant planets with separations beyond the ``snow
line.'' I then discuss the near and long-term prospects for microlensing planet
searches, and in particular speculate on the expected returns of
next-generation microlensing experiments both from the ground and from space.
When combined with the results from other complementary surveys, next
generation microlensing surveys can yield an accurate and complete census of
the frequency and properties of essentially all planets with masses greater
than that of Mars.
