Radiative Electroweak Parameters

The status of the present precision measurements of electroweak observables is reviewed with specific reference to the radiative parameters $S,T,U$ or equivalently $ε_1,ε_2,ε_3$. The significance of the obliqueness hypothesis is underlined and the importance of the ``local fit'' method of extracting these parameters from the data is emphasized. Possible new physics implications are briefly touched upon.
