Custom meia is a marketing term referring broadly to the development, production and delivery of media (print, digital, audio, video, events) designed to strengthen the relationship between the sponsor of the medium and the medium's audience. Also called, branded media, customer media, member media, content marketing, and custom publishing, custom media is different from traditional media in very subtle, yet significant ways: Typically, custom media is sponsored by a single marketer (a company, association or institution) and is designed to reach a tightly focused audience of customers, members, alumni or other constituency. Custom media can be produced "in-house" by such organizations. Over the past two decades, a growing number of specialized publishing and media firms have emerged called "custom media" or "custom publishing" companies. Like advertising and other marketing services firms, the companies or divisions of traditional media companies, provide professional marketing and communications services to clients for a fee. Such out-sourced services can be limited to design and editorial responsibilities or include the complete production and distribution process.
