Nielsen and Gfk Begin a Collaboration in the Book Industry

London, Oct. 26, 2015 – A strong partnership for top-quality data—two of the world’s leading market research institutes, Nielsen and GfK, are forming a partnership for targeted future cooperation within the book sector. This agreement was announced by the two companies to coincide with the Frankfurt Book Fair. The new cooperation is a milestone for international market research in the book industry. The collaboration is intended to help customers identify multinational trends and to more closely observe market developments. GfK and Nielsen have been investigating sales and consumer data across all sales channels in numerous countries for decades.

At the core of the cooperation are key figures from the world’s largest audience market in the U.S., as well as from the U.K., the second largest book market in Europe. This industry-specific information obtained from Nielsen will be integrated into the GfK databases and provided to customers via the connected web tools. They provide a valuable overview of bestsellers, hot topics and successful authors in different genres, and enable conclusions on sales traffic in other countries such as Germany, Austria and Switzerland to be made.

Dr. Mathias Giloth, managing director of GfK Entertainment: “Which books from the U.K. might become bestsellers in Germany? What kind of hype is sweeping across the U.S.? The global success of titles such as “Girl on the Train” or “Diary of a Wimpy Kid” is causing the industry to ask these types of questions, because the book trade is changing. We are looking forward to providing a better overview of an increasingly internationalized market environment. Bringing together data from Nielsen and GfK is a crucial foundation for this.”

Jonathan Stolper, senior vice president and global managing director of Nielsen Book, said “Having operated independently for many years, it is very exciting to be working with GfK, and we hope this collaboration between the two companies will be a powerful proposition for clients and prospective clients. Our aim is to deliver market data that our clients need to fulfil their business requirements, wherever they are based. We anticipate that including the Anglo-American market data in the GfK modules will be the first step of a long-term collaboration between Nielsen and GfK in the field of book research. “
