• This is an extensive survey on the Meyer-König and Zeller operators. It includes most of the modifications they have undergone through the years, in particular the well-known Cheney and Sharma operators and their own modifications. The organization of the exposition refers to papers whose goals are connected with the study under consideration in each section rather than their chronological appearance. The results obtained by the different authors have been commented.
