The electrodynamics of active continuous media is used to theoretically examine collective spontaneous emission regimes of dipole oscillator ensembles. Recent experiments that observed the superfluorescence phenomenon are reviewed. The focus is on propagation and interaction effects experienced by the inhomogeneous waves of active centers' polarization and electromagnetic field. The superradiant laser dynamics are examined and prospects for realization of superradiant lasers using low-Q cavities are discussed.
