Definition: In the media sector, niches often correspond to very specialized content. Theorized by Chris Anderson, the niche constitutes the “long tail” of certain entrepreneurs. These products find few buyers but are in such a number that they represent a significant mass. For example, the Amazon e-commerce site offers country records from the 50s. These are intended for some connoisseurs and will not be bought very often. However, the site also offers a multitude of other “specialized” music records and therefore finds a real interest in making all these “niche” products available.
