The Darwin Industry refers to historical scholarship about, and the large community of historians of science working on, Charles Darwin's life, work, and influence. The term "has a slightly derogatory connotation, as if the scale of the research has gotten out of control with people cranking out studies on perhaps less and less important aspects of Darwin's work"; but it was originally a self-designation of the scholars who began re-evaluating Darwin and studying his manuscripts and correspondence in the second half of the 20th century.
