I will review recent progress on the nonperturbative studies of nearly conformal gauge theories which provide a mechanism to replace the conventional Higgs sector of the standard model. The conformal window is identified in these theories in different flavor and color representations by establishing the chirally broken phase and the fixed point of the running gauge coupling. Reliable results are beginning to emerge from lattice calculations by matching to low energy Goldstone dynamics and random matrix theory. The running coupling is determined from the renormalization behavior of Wilson loops and from the Schrodinger functional. The challenges and difficulties of the calculations, unlike the ones in QCD, will be reviewed as well.
