  Radio-loud AGN are characterized by relativistic jets originating near the
central supermassive black hole and forming large-scale radio sources at parsec
to kiloparsec to Megaparsec distances. The jets are energetically significant,
in many cases representing the bulk of the energy extracted from the accretion
process. Host galaxies are apparently normal luminous ellipticals, supporting
the "Grand Unification" scenario wherein AGN are a transient phase in the
evolution of every galaxy. Black hole mass appears to be largely uncorrelated
with bolometric luminosity, Eddington ratio, radio luminosity, or radio
loudness.
