Resonant Inelastic X-ray Scattering (RIXS) has undergone enormous theoretical and experimental development in recent years - to the point where the technique is now able to observe all the relevant low energy excitations, including phonons, magnons, orbital excitations, charge transfer excitations, etc. As a result it is now able to make significant contributions to many of the current hardest problems in condensed matter physics. Here I provide an overview of the technique, and its development, focusing on the hard x-ray regime. In particular, I review work on the cuprates, the observation of two-magnon scattering and the very recent work on the low energy excitations of the iridates including the observation of mixed spin and orbital excitations. Finally I conclude with a brief discussion of the exciting prospects for the future of this technique.
