Abstract
From phenomenological and field-theoretical considerations on photon mass, we first show that photon is not limited to being massless at the present stage. Next we illustrate a possibility of formulating a local field theory for massive photons coupled with nonconserved currents, while we cannot formulate it for massless photons.
