A substantial off-shell Higgs boson signal in the gluon fusion and vector boson fusion H --> ZZ and H --> WW channels at the Large Hadron Collider (LHC) facilitates a novel, complementary approach to constraining the total Higgs width GammaH. With LHC Run 1 data, experimental analyses by CMS and ATLAS find GammaH < 5.4 GammaH,SM and GammaH < [4.5,7.5] GammaH,SM at 95% confidence level, respectively, where GammaH,SM is the expected value in the Standard Model at the measured Higgs boson mass. I review the theoretical basis of the new approach and discuss its significance in comparison to other methods to bound and measure the Higgs width at the LHC and future colliders.
