text: The VERITAS array of four 12-m diameter imaging atmospheric-Cherenkov telescopes in southern Arizona is 
  used to study very high energy (VHE; E>100 GeV) γ-ray emission from astrophysical objects. VERITAS is 
  currently the most sensitive VHE γ-ray observatory in the world and one of the VERITAS collaboration’s Key 
  Science Projects (KSP) is the study of blazars. These active galactic nuclei (AGN) are the most numerous class 
  of identiﬁed VHE sources, with ∼30 known to emit VHE photons. More than 70 AGN, almost all of which 
  are blazars, have been observed with the VERITAS array since 2007, in most cases with the deepest-ever VHE 
  exposure. These observations have resulted in the detection of VHE γ-rays from 16 AGN (15 blazars), including 
  8 for the ﬁrst time at these energies. The VERITAS blazar KSP is summarized in this proceeding and selected 
  results are presented.
