This article summarizes recent Tevatron and LHC measurements of W/Z production in association with inclusive jets. The differential cross sections are measured as a function of jet multiplicity and various kinematic variables of jets or W/Z boson. Third-jet emission probability, angular correlations among reconstructed objects, and an event shape variable are studied. A first measurement of electroweak production cross section of the Z boson with two forward-backward jets is also presented. All results are compared to next-to-leading order perturbative QCD calculations and predictions of simulations that interface matrix-element calculations with parton showers. These studies constrain the backgrounds to searches for physics beyond the standard model.
