Massive stars dominate the chemical and dynamical evolution of the ISM, and ultimately of their parent galaxy and the universe, because of their fast evolution and intense supersonic winds. Decades ago, the advent of space-born UV spectroscopy marked the discovery of mass loss in massive stars and began to change our understanding of their evolution. Recently, significant advances in stellar modelling, and the observation of crucial ions in the far-UV spectral range disclosed by FUSE, led to resolve long-standing issues in modelling massive star winds and atmospheres, and to assess of the roles of shocks and clumping. A revised (downwards) calibration of Teff for early spectral types emerged as a result. Meanwhile, HST imaging had opened the possibility of detailed resolved studies of stellar populations in Local Group galaxies, sampling a variety of metallicity and environment conditions. More recently, GALEX is providing the first global, deep view of the massive star populations for hundreds of nearby galaxies. The unprecedented coverage and sensitivity of the GALEX UV imaging, easily detecting extremely low levels of SF, is once again revolutionizing some of our views of massive star formation in galaxies.
