 \section{Introduction}
 
-The age of synoptic surveys has come.  As optical (and other
-wavelength) telescopes are surveying ever increasing areas to ever
-fainter flux limits with multiple repeats, there is a growing interest
-in the study of transient phenomena.  This technological progress is
-well matched with the current scientific emphases on large samples of
-supernovae (SN), microlenses, asteroids, and other transients and
-variable sources.
+The past three decades have seen the increasing importance of
+time-domain surveys in astronomy.  These include asteroid searches
+such as the Lincoln Near-Earth Asteroid Research
+\citep[LINEAR][]{2000Icar..148...21S}, the Lowell Observatory
+Near-Earth Object Search \citep[LONEOS,][]{1995DPS....27.0110B}, the
+Catalina Sky Survey \citep{2003DPS....35.3604L}, and ATLAS
+\citep{2018PASP..130f4505T}; microlensing surveys such as MACHO
+\citep{1993ASPC...43..291A} and Optical Gravitational Lens Experiment
+\citep[OGLE,][]{1992AcA....42..253U}; and searches for supernovae and
+other transient sources such as ASAS-SN \citep{2014ApJ...788...48S}, the
+Palomar Transient Factory \citep[PTF,][]{2009PASP..121.1395L}, and the Robotic Optical
+Transient Search Experiment \citep[ROTSE-I,][]{2000ApJ...542..251A}.
+
+The Pan-STARRS Observatory \citep{chambers2017} has been a leader in
+the searches for both explosive transient / supernova and potentially
+hazardous asteroids.  According to the statistics maintained by David
+Bishop\footnote{http://www.rochesterastronomy.org/snimages/archives.html},
+since 2009, 40\% of all supernova have been discovered by
+Pan-STARRS\,1.  Similarly, 24\% of all Near Earth Objects (NEOs)
+discovered to date have been found by
+Pan-STARRS\footnote{https://cneos.jpl.nasa.gov/stats/site\_all.html}.
+Since 2014, when Pan-STARRS shifted its primary mission to the search
+for NEOs, this fraction has increased to 41\%. Both of these search
+programs use nightly observations to hunt for features which have
+changed, either between multiple images in a single night or between
+the current image and an archival reference image.
