We reconsider the options for cosmological holography. We suggest that a global and time-symmetric version of the Fischler-Susskind bound is the most natural generalization of the holographic bound encountered in AdS and De Sitter space. A consistent discussion of cosmological holography seems to imply an understanding of the notion of ''number of degrees of freedom'' that deviates from its simple definition as the entropy of the current state. The introduction of a more adequate notion of degree of freedom makes the suggested variation of the Fischler-Susskind bound look like a stringent and viable bound in all 4-dimensional cosmologies without a cosmological constant.
