We point out that the nonempty $R_h=ct$ cosmological model has some known
antecedents in the literature. Some of those eternal coasting models are
published even before the discovery of the accelerated expansion of the
universe and were shown to have none of the commonly discussed cosmological
problems and also that $H_0t_0=1$. The $R_h=ct$ model is only the special
(flat) case of the eternal coasting model. An additional feature in the
coasting model is that $Omega_m/Omega_{dark ; energy}$ = some constant of
the order of unity, so that also the cosmic coincidence problem is avoided.
