I will briefly review here the main results obtained by the high-energy missions SIGMA/GRANAT, Compton-GRO, Beppo-SAX and Rossi-XTE, on these objects and, in particular, I will discuss the spectral shapes observed at energies higher than 30 keV and the detections of high energy features at > 300 keV. Galactic black holes are indeed main targets for the ESA gamma-ray mission, INTEGRAL, to be launched in October 2002, and for the next gamma-ray missions SWIFT, AGILE and GLAST. We expect that a large amount of data will be collected in the next years and the perspectives for the high energy astrophysics of galactic black hole systems look very promising.9 pages, including 8 figures, submitted 15 July 2002, to appear in the proceedings of the XXII Moriond Astrophysics Meeting "The Gamma-Ray Universe" (March 9-16, 2002, Les Arcs, France), eds.
