A number of quasars show the peaks of their broad emission lines at very different redshifts from their narrow emission lines. Two examples are illustrated. This difference could well be present to some degree in all quasars. Relative blueshiftings and redshiftings appear to be equally common. Some objects in addition show two displaced broad line peaks one blueshifted and the other redshifted. It is proposed that these displaced broad line peaks are the result of orbital motion of two supermassive objects, each with its own associated broad line region. Such binaries could arise in a number of ways during the evolution of a galactic nucleus. The observed velocities (approximately 3000 km/s) are consistent with the expected evolution of supermassive binaries as predicted by Begelman, Blandford and Rees (1980).
