The past decade has shown an exponential growth in the number of
transiting extrasolar planets. Such systems are extremely valuable,
since they reveal key astrophysics of these planets, such as mass,
radius, internal structure, atmosphere, orbital inclination with
respect to stellar rotation, among many others.  The HATNet program,
with relatively modest instrumentation, is one of the most successful
searches, and has contributed at least seven planets to the growing
sample. HATNet employs six wide-field cameras, each 10 centimeters in
diameter, that are arranged in a network of two stations: Arizona
(Whipple Observatory) and Hawaii (Mauna Kea). I will give an overview
of the project, and will take the audience through the basic steps of
the 'hunt', briefly discussing the observing technique, transit
recovery rate, number and classification of false positives, and
confirmation of planets. I will describe the HATNet planets, and place
them in a broader context. I will close the talk by mentioning
HAT-South, a new project that is expected to outperform HATNet by an
order of magnitude.
