Corollary genre

A genre variation engendered when actors revise some of the discursive qualities and expectations of a particular genre but do not completely transform the genre itself. Such modifications bring about derivative or 'corollary' genres (Yates & Orlikowski, 2007).

Example:

The Powerpoint "deck," which is designed to be printed and delivered to a client, rather than visually displayed to support an oral presentation (Yates & Orlikowski, 2007).
