  Low energy (1-loop) constraints on anomalous triple gauge boson vertices
(TGV's) are revisited and compared to the sensitivity achievable at LEP II and
at future linear $e^+e^-$ colliders. The analysis is performed within the
framework of an effective Lagrangian of gauge invariant dimension six operators
with the gauge bosons and a single Higgs doublet field as the low energy
degrees of freedom. The low energy data do not directly bound TGV's but they
provide strong constraints on models which lead to anomalous gauge boson
interactions in addition to other low energy effects.
