Description
CMB spectral distortion measurements are going to be challenging and multiple groups are considering experimental approaches that might allow us to target these small signals in the near and distant future. In my talk I will give a brief overview of all the ongoing and planned CMB spectrometer concepts and initiatives trying in particular to highlight synergies and individual strengths. I will then address the question about what is still needed for us to take major steps forward and how we might start to get organized with this ambitious goal.
