Think of the group of consumers interested in purchasing cleaning services, for instance. Instead of offering general cleaning services, a business might establish a niche market by targeting the portion of this market interested in blind cleaning services. Another business might occupy its own niche in this market by specializing in using only environmentally friendly cleaning products. Markets of any discernible size contain multiple subsets of potential markets - although not all of the possible niche markets will be worth targeting from a business point of view.
Unlike mass audiences, which represent a large number of people, a niche audience is an influential smaller audience. In television, technology and many industrial practices changed with the post-network era, and niche audiences are now in much greater control of what they watch. In this context of greater viewer control, television networks and production companies are trying to discover ways to profit through new scheduling, new shows, and relying on syndication. This practice of "narrowcasting" also allows advertisers to have a more direct audience for their messages.
