  The fine-scale structure and the kinematics of relativistic active galactic
nuclei (AGN) jets have been studied by very-long-baseline interferometry at
very high resolutions since 1998 at 2 cm wavelength for a sample of over a
hundred radio sources (VLBA 2cm Survey and MOJAVE programs). Since 2007, this
is being complemented by the TANAMI project, based on southern observations
with the Australian LBA at 3.6 cm and 1.1 cm wavelengths. From our observation
campaign, we find that most of the radio jets show linear morphologies at
parsec-scales, but some of show curvature and non-radial motions. Features are
observed to move at highly relativistic speeds, with Lorentz factors extending
above values of 30. We also provide a brief description of the relationship of
our radio findings with the AGN observations by the new Fermi Gamma-ray Space
Telescope.
