Since the discovery of quasars, it has been recognized that these objects must have either an extraordinary intrinsic brightness or a nonlinear redshift. Astronomers have generally preferred a linear (Hubble) redshift-distance relation and time evolution within a Big Bang model. We reconsider the possibility of a nonlinear (de Sitter) redshift-distance relation and find quasar absolute magnitudes to be rather ordinary. Given a de Sitter law, absolute magnitude is found to be independent of redshift over five orders of magnitude.
