Multi-wavelength emission models in blazars.

I will discuss the most recent results about blazars, coming mostly from the Fermi and Swift satellites, but also on searches of high-z blazars with the SDSS and FIRST. Then I will present the main properties of blazars as derived by modelling, focusing on the Flat Spectrum Radio Quasar class. For them the accretion disk emission can be visible, allowing the measurement of the black hole mass and the accretion rate. I will discuss where we stand about the understanding of blazar physics.
