The three massive gauge boson VVV (V = W, Z) production at
the LHC is interesting because measurements of such processes can
probe the interactions between massive bosons including the Higgs. Up
until recently, such measurements have remained elusive because of low
production cross sections. This talk will discuss the recent CMS
result of first observation (5.7σ) of combined VVV production at the
CERN LHC and evidences for WWW (3.3σ) and WWZ (3.4σ) productions
individually. Finally, I will briefly discuss the future of the
physics program of the rare multi-boson processes.
