In this review we highlight what has been gained from a host of surveys covering a large proportion of the electromagnetic spectrum with respect to active galactic nuclei with emphasis placed on the powerful high‐redshift radio galaxies and radio‐loud quasars. We focus on recent results which consider the cosmic evolution of radio galaxies and radio‐loud quasars, their host galaxies and black‐hole masses. We then briefly highlight the potential of combining surveys at other wavelengths, such as the SDSS and Spitzer surveys, for investigating these topics. Finally, we look forward to the new parameter space which will be opened up with the radio telescopes of the future, namely the LOFAR and the SKA. These new telescopes are likely to lead to a shift in radio survey science. The survey depths that are within the reach of these telescopes will mean that the dominant populations will no longer be AGN, but starburst and ‘normal’ galaxy populations out to z ≳ 2. However, the SKA will also have the ability to find and measure redshifts for every moderately powerful radio AGN in the Universe, providing a new and unique view of galaxy formation and evolution.
