We survey the development and status quo of a subject best described as “generic representation theory of finite dimensional algebras”, which started taking shape in the early 1980s. Let \({\Lambda }\) be a finite dimensional algebra over an algebraically closed field. Roughly, the theory aims at (a) pinning down the irreducible components of the standard parametrizing varieties for the \({\Lambda }\)-modules with a fixed dimension vector, and (b) assembling generic information on the modules in each individual component, that is, assembling data shared by all modules in a dense open subset of that component. We present an overview of results spanning the spectrum from hereditary algebras through the tame non-hereditary case to wild non-hereditary algebras.
