Abstract: A large fraction of the AGNs detected by EGRET exhibit strong variability in many wavebands- from radio to the highest energy gamma-rays observed. The origin of the transient emission in blazars is presumably associated with relativistic jets. In this talk I will discuss plausible variability mechanisms that may operate in blazars. In particular, dissipative fronts produced by unsteady ejection of magnetized, relativistic outflow, one zone emission models with time-dependent particle acceleration, and Compton scattering of external radiation with time varying intensity will be considered. The implications for the TeV BL Lac objects will be emphasized.
