We present an overview of measurements of electroweak vector boson pair
production and anomalous Triple Gauge Couplings (aTGC), with semileptonic and
fully leptonic final states. The data analyzed were taken at center of mass
energy of 7 & 8 TeV by the CMS detector at the Large Hadron Collider. The
cross-section measurements are important because they are test of the Standard
Model predictions, while these processes serve as background for Higgs searches
and various other processes
