Description
Relativistic jets in AGN emit radiation at all wavelengths,
from radio to TeV gamma-rays. The main source of their power seems the rotation of the black hole. Their radiation mechanisms however remains elusive. I will review the current status and some recent observations which are challenging
common views, in particular about variability, location of the gamma-ray emitting regions, particle acceleration and main emission mechanisms among different classes of sources.
