  In this survey, we have attempted to show some developmental milestones on
the characterizations of intersection graphs of hypergraphs. The theory of
intersection graphs of hypergraphs has been a classical topic in the theory of
special graphs. To conclude, at the end, we have listed some open problems
posed by various authors whose work has contributed to this survey and also the
new trends coming out of intersection graphs. Keywords: Hypergraphs,
Intersection graphs, Line graphs, Representative graphs, Derived graphs,
Algorithms (ALG), Forbidden induced subgraphs (FIS), Krausz partitions,
Eigenvalues.
