Over the last decades, the high-energy heavy-ion collisions at RHIC and the LHC allowed the exploration of QCD at high energies and densities. In these experiments, the nuclear matter is produced far from equilibrium, and undergoes a multiphase evolution. In one of the intermediate stages of the system's evolution, the matter thermalizes into a nearly ideal liquid: the quark-gluon plasma. The main effort of the heavy-ions community is focused in extracting the detailed properties of this phase of matter. To do that, since one can not measure the quark gluon plasma directly, indirect probes are necessary. One of the most successful of such probes are jets, which due to their multiscale nature, provide an optimal window into the details of the quark gluon plasma's evolution and structure. In this talk, I will review the basic theoretical formalism used to describe jet evolution in the medium and some classical results. Then, I will give an overview of more recent developments in theory and phenomenology, pointing out possible future directions in this field.
