Black hole feedback results from the energy radiated at parsec scales from the centers of massive galaxies. Yet, this process is energetic enough to regulate the evolution of the host galaxy itself. We present here observational evidence suggesting that, in the most massive halos, black hole feedback from the central galaxy is able to drive the evolution of the satellite population, megaparsecs away from the center of the halo. Moreover, this large-scale feedback leaves its energetic imprint on the thermodynamics of the intracluster medium, as halos hosting more massive black holes are heated more efficiently above the virial temperature.
