Abstract: The early universe was dominated by a small number of giant galaxies containing colossal black holes and prodigious bursts of star formation. More recently, the creation of stars and the accretion of material into black holes has been taking place in a large number of medium-size and small galaxies. I will present observations made at many different wavelengths that show this vast downsizing of cosmic activity.
