Recently, LHC experiments reported an observation of the new particle in the search for the Higgs boson with a mass of ~125 GeV decaying to predominantly to gammagamma and ZZ. To confirm this particle to be a Higgs boson, it is necessary to establish that it decays to the final states with b-quarks. I will discuss searches for the SM Higgs boson in the final state with b-quarks with the D0 experiment at the Tevatron, highlighting the most important techniques. These results lead to the evidence of a new particle consistent with the standard model Higgs boson produces in association with a vector boson which decays to a bottom-antibottom quark pair. I will also draw a parallel with current and future searches at the LHC, showing what we can learn from our Tevatron experience. I will emphasize the future direction of the LHC experiments in light of a discovery consistent with the signature of the Higgs boson.
