This paper, which is dedicated to Prof. Bernard Delmon for his outstanding contributions to heterogeneous catalysis, will only encompass his remarkable findings in the field of spillover phenomena. In a certain way, this paper is not a new additional review about spillover itself, i.e. its formation, but an attempt to highlight the many parts spillover can play in catalysis in general and the implications of Bernard Delmon and his various teams in particular. Of course much will be described about the remote control concept but not exclusively. On the eve of the 5th International Conference on Spillover (5th ICSP) to be held in Madrid in September 2001, it is of particular interest to try getting a good picture of how the spillover-baby has grown up since its experimental discovery in the 1960s.
