Hadro‐production data on charm and beauty absolute cross‐sections, collected by experiments at CERN, DESY and Fermilab, are reviewed. The measurements, corrected for the ‘time evolution’ of the branching ratios, are compared to calculations done with Pythia, as a function of the collision energy, using the latest parametrizations of the parton densities. We then estimate some charm and beauty production cross‐sections relevant for future measurements, including nuclear effectes in the PDFs. We finish by briefly addressing the relevance, in heavy‐ion collisions, of beauty production as feed‐down for J/ψ production.
