In the past six years, the number of known extragalactic TeV sources increased from a handful to currently 45, thanks to the new generation of instruments like H.E.S.S., MAGIC and VERITAS. The dominating source species constitute Active Galactic Nuclei, specifically high peaked BL Lacertae objects (HBLs). However, still our understanding of the physics occurring in these objects is rather limited, owing to the strong variability of the emission from minutes to month timescale as well as their broadband emission from radio up to TeV energies. The most pertinent way to increase our knowledge are simultaneous multi-wavelength (MWL) observations. In this talk, the results of the first TeV MWL campaigns on 1ES 1011+496 and Mrk 180, two HBLs discovered by MAGIC, will be presented. From the radio up to the TeV regime, RATAN-600, VLBA Effelsberg, Metsähovi, KVA, Swift, AGILE, Fermi and MAGIC were contributing to the campaigns in 2008.
