Abstract. The global Standard Model (SM) electroweak fit has a long tradition in particle physics. It exploits the enormous amount of pioneering work in the calculation of radiative corrections in electroweak physics as well as precision measurements at the Z-peak by the LEP and SLD collaborations. In the recent past precision measurements of the top quark and W boson mass by the Tevatron experiments have complemented the available precision data. In view of the discovery of a new boson with Higgs-like properties by the ATLAS and CMS collaborations an update of the global fit to electroweak precision data is presented. The new boson is assumed to be the SM Higgs boson, which allows for the first time to overconstrain the SM at the electroweak scale and assert its validity. In this talk I will review the status of the electroweak fit and the constraints on new physics through the oblique vacuum corrections. I will conclude with an outlook showing the impact of precision measurements at a possible future linear collider.
