The last several years have seen a revolution in measurements of the anisotropy of the cosmic microwave background (CMB). These measurements represent a unique opportunity to probe the density and velocity structure of the Universe as it was at a tiny fraction of its current age, and when the physics was still simple linear perturbations. I will describe results from the DASI experiment at the South Pole which was the first to observe CMB polarization, WMAP results and their implications, and the new polarimeter QUaD which has just completed its first season of operation at Pole.
