For over three decades, the giant elliptical galaxy M87 has hosted the most massive known black hole in the local universe. Recent measurement of the shadow size of this black hole by the Event Horizon Telescope confirmed a mass of 6 billion suns determined earlier from stellar kinematics. I will review the current state of dynamical mass measurements of supermassive black hole and discuss the progress in discovering black holes beyond 10 billion solar masses. State-of-the-art integral-field spectrographs are essential for uncovering this new population of black holes, which is challenging the standard co-evolution paradigm of black holes and their host galaxies.
