This review describes the discovery of the cosmic microwave background (CMB) radiation in 1965 and its impact on cosmology in the 50 years that followed. This discovery established the big bang model of the Universe, and the analysis of its fluctuations has confirmed the idea of inflation and led to the present era of precision cosmology. I discuss the evolution of cosmological perturbations and their imprint on the CMB as temperature fluctuations and polarization. I also show how a phase of inflationary expansion generates fluctuations in the spacetime curvature and primordial gravitational waves. In addition I present the findings of CMB experiments, from the earliest to the most recent ones. The accuracy of these experiments has helped us to estimate the parameters of the cosmological model with unprecedented precision, so that in the future we shall be able to test not only cosmological models but general relativity itself on cosmological scales.

At low frequencies f<10 16 Hz, this SGWB is also the target of CMB experiments, through the measurement of the B-mode polarisation (for a complete treatment, see e.g. [95]). The present upper bound by the Planck satellite on the tensor to scalar ratio is r<0:07 [1”
