Argument From Age (Wisdom of the Ancients): snobbery that very old (or
very young) arguments are superior. This is a variation of the Genetic
Fallacy, but has the psychological appeal of seniority and tradition
(or innovation).
Products labelled "New! Improved!" are appealing to a belief that
innovation is of value for such products. It's sometimes true.

Genetic Fallacy (Fallacy of Origins, Fallacy of Virtue): if an
argument or arguer has some particular origin, the argument must be
right (or wrong). The idea is that things from that origin, or that
social class, have virtue or lack virtue. (Being poor or being rich
may be held out as being virtuous.) Therefore, the actual details of
the argument can be overlooked, since correctness can be decided
without any need to listen or think.

This is the opposite of the appeal to tradition;
Appeal to Tradition is a fallacy that occurs when it is assumed that
something is better or correct simply because it is older,
traditional, or "always has been done."

Arguments from "age" and "tradition" as varients of arguments to the
"genetic" could be combined as the general "genetic" was above;
Appeals to Tradition and Age are fallacies that occur when it is
assumed that something is better or worse, correct or incorrect,
simply because they are older/newer, traditional/contemporary, or
"always has been done"/"this is the new way."
