  The single Higgs doublet in the standard model (SM) may be the simplest way
of introducing electroweak symmetry breaking, but SM extensions with more
scalar doublets are not excluded. A special case of the two Higgs doublet
models is the inert doublet model - a minimalistic version with interesting
phenomenology. These proceedings reviews the inert doublet model's theoretical
setup, constraints, collider prospects and its dark matter phenomenology.
