Abstract: The emission processes in active galactic nuclei and particularly of blazars are still far from clear. Their extraordinary high luminosity and their strong variability on very short time scales favour an origin of the radiation within a relativistic jet. Despite the general agreement of this picture a variety of competing models based on the relativistic jet scenario are capable to explain the spectral energy distribution of blazars for a single epoch. Investigating the spectral evolution of pronounced variability patterns throughout the spectrum will be a more sensitive test to the models. We have monitored the strongly variable BL Lac object S5 0716+710 ranging from the mm-regime to the gamma-rays. We present the spectral evolution of the high energy regime up to the EGRET band and discuss the impact of our results on recent models for blazar emission.
