  Results are presented from long term VLBI monitoring of the parsec-scale
radio jet in 3C120, primarily at 5 and 1.7 GHz. Numerous superluminal features
are followed, some over large fractional distances from the core. The speeds of
the features are not all the same, but vary by less than a factor of 2. The
superluminal features extend to core distances of over 0.2 arcseconds and the
region of slowing has not been found. The 1.7 GHz images show evidence for
stationary features in addition to the superluminal features. The structure of
the jet in the vicinity of the most likely stationary feature is suggestive of
a helical pattern seen in projection. The deprojected wavelength of the pattern
is very long relative to the jet radius, unlike the situation in sources such
as M87. If the 3C120 jet does contain a slowly-moving, helical structure, then
theory suggests that the jet resides in a relatively cool medium, not in a
relativistically hot cocoon or lobe.
