  A simple model of uniformly expanding, homogeneous Universe with a bulk
viscosity is studied wherein the inflationary density decays due to viscous
dissipation during the expansion phase of the Universe. The model is shown to
generate the Cosmic Microwave Background radiation (CMB). We also demonstrate
that, at late times, the inflationary density asymptotically approaches a small
finite constant value.
