Multiwavelength (MW) observations are an essential diagnostic tool to study the physics of blazars. Blazars, the most extreme objects among the Active Galactic Nuclei (AGNs), are characterized by rapid variability at all wavelengths from radio through TeV γ-rays. Considerable progress has been made in recent years thanks to multiwavelength monitoring campaigns. In this contribution, I will give a brief overview of the MW campaigns carried out in the past by large collaboration and their impact on the knowledge of the most important source/jet parameters needed by the physical models used to fit the observed blazar spectral energy distribution (SED). Furthermore, I will discuss some of the perspectives for multiwavelength observations during the operation of the gamma-ray mission GLAST.
