  I review the status of the search for quark-gluon plasma in relativistic
heavy-ion collisions. The available data provide strong evidence for the "three
pillars of the Little Bang model": strong radial expansion of the collision
fireball with Hubble-like scaling, thermal hadron emission and primordial
hadrosynthesis. It is argued that the initial state of the reaction zone
exhibits features which cannot be understood with conventional hadronic
dynamics, but are consistent with the formation of deconfined quark-gluon
matter.
