Affiliate marketing, a sort of product placement, will let you receive nice checks from companies in return for advocating for their goods and services. Although this might sound a bit iffy, if you truly do recommend that your readers try out these products, then it doesn’t need to come across as sales-y or insincere. Readers will understand that you need to make money somehow, and many will appreciate your recommendations if they’re accurate.
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.
