An overview of the physics of heavy quark production at collider experiments is presented. Recent measurements of open charm and beauty production and of charmonium at HERA, LEP and the Tevatron are reported. The data are compared with each other and with predictions from perturbative QCD calculations. The main results from charmonium measurements at the B-factories are discussed and some of the recently discovered new resonance states are presented.
