Blazar observations above 100 GeV with VERITAS
  The VERITAS array of 12-m atmospheric-Cherenkov telescopes in southern
Arizona is one of the world's most-sensitive detectors of very-high-energy
(VHE, E>100 GeV) gamma rays. More than 50 extragalactic sources are known to
emit VHE photons; these include blazars, radio galaxies, and starburst
galaxies. Blazar observations are one of the VERITAS Collaboration's Key
Science Projects. More than 400 hours per year are devoted to this program and
~100 blazars have already been observed with the array, in most cases with the
deepest ever VHE exposure. These observations have resulted in 21 detections,
including 10 VHE discoveries, all of them with supporting multiwavelength
observations. Recent highlights from VERITAS extragalactic observation program
and the collaboration's long-term blazar observation strategy are presented.
