Mass accretion onto super massive black holes is a key process to power active galactic nuclei. Radio interferometry is a powerful tool to quest the accretion matter and the mechanism to subtract its angular momentum. I will review studies of masers and absorption studies of some molecules, HI, and plasma in the circumnulear region.
