Quasars have been studied now for a bit longer than 50 years, and other types of active galaxy for a few decades longer. The overall aim of
SED (spectra energy distribution) studies is to associate the energy emitted across various frequency ranges with physical processes common to all AGN. Once this  has been achieved we can then investigate the physics of each component, and  look for relationships between them. I will describe in broad terms what factors determine the SEDs for some well studied samples of AGN, and finish with some future prospects for advances using near future facilities, such as the James Webb Space
Telescope, the Cherenkov Telescope Array and planned large surveys.
