  The precision electroweak program, including weak neutral current (WNC),
$Z$-pole, and high energy collider experiments, has been the primary prediction
and test of electroweak unification. It has established that the standard model
(SM) is correct and unique to first approximation, establishing the gauge
principle as well as the SM gauge group and representations; shown that the SM
is correct at loop level, confirming the basic principles of renormalizable
gauge theory and allowing the successful prediction or constraint on $m_t$,
$\alpha_s$, and $M_H$; severely constrained new physics at the TeV scale, with
the ideas of unification strongly favored over TeV-scale compositeness; and
yielded precise values for the gauge couplings, consistent with
(supersymmetric) gauge unification.
