  The TANAMI VLBI program is monitoring a sample of 84 Active Galactic Nuclei
of the Southern Sky at 8.4 and 22 GHz. The combination of VLBI and
multiwavelength data allows us to study changes in the spectral energy
distributions, as well as changes in the structure of the inner jets and to
search correlations between both. We present initial results of the
multiwavelength analysis of a sub-sample of the TANAMI sources, combining our
radio data with simultaneous X-ray and optical/UV observations from Swift and
XMM-Newton, and gamma-ray data from Fermi, focusing on the broadband spectral
energy distributions as well as variability in different wavebands.
