The idea of dark forces - new gauge interactions with small couplings to the Standard Model particles and interaction ranges accessible in medium energy collisions - has remained on the back burner of particle physics for almost three decades. During the last two years, however, this subject has become a focal point due to the new exciting developments that tie the combination of dark forces and particle dark matter to the newly discovered cosmic ray anomalies. Here we review this new motivation for studying dark forces, and give an account of the contribution of Perimeter Institute to the development of new search strategies of dark forces in particle physics experiments.
