A detailed account of what happened in the theory of mean convergence of Lagrange and Hermite-Fejér type interpolation in the last fifty-five years is given. Starting from the classical result of Erdo{combining double acute accent}s and Turán, (hopefully) all important developments are considered, in some cases with an indication of the method of proof. Even some yet unpublished results are included. A list of references helps to orientate those interested in the details. © 1992.
