In order to build a successful media business today, publishers must have a strong data foundation. Everything a publishers does, from content to advertising and events, relies on robust audience data files. If cash is king in the financial world, than data is king in the publishing world, says publishing management and sales consultant John French. The size of one's audience is not necessarily important today, adds French; rather, the detail and usability of a publisher's audience file is much more valuable. In this video French explains why audience data is such a crucial component to a publishing business and what publishers can do to get their data in order. French is co-founder of French LLC., an advisory firm aimed at helping media executives transforming their companies for a digital- and data-driven world.
