---- Abstract -----

This paper discusses and criticizes the usual definitions of barriers to entry. The failure of the concept of barrier to entry to incorporate a time dimension means that it is a concept that is in need of additional embellishment in order to be useful in a practical problem or for antitrust or regulatory proceedings.
