The temporal evolution of certain aggregates of particles -- of neutrons in a multiplying medium, of electron-photon cascades in cosmic rays, say -- can be successfully modeled via so-called branching processes. A brief overview of the most popular classes of branching processes is given. In particular the continuous-time Bienaymé-Galton-Watson processes and continuous-state branching processes are described as time-changed Lévy processes that are ``skip-free downwards''.
