Britain's Pearson to invest $89.5 million in Barnes & Noble's Nook Media Fri Dec 28, 2012 9:54am EST (Reuters) - British education and media publisher Pearson Plc said it will buy a 5 percent stake in Barnes & Noble Inc's digital Nook and college bookstore businesses for $89.5 million. Barnes & Noble, whose shares rose as much as 6 percent to $15.19 on the New York Stock Exchange on Friday morning, said the Nook division will not meet prior expectations for its current year. The top U.S. bookstore chain's Nook Media unit comprises its digital businesses - including Nook e-reader and tablets and the Nook digital bookstore - and 674 college bookstores across America. Barnes & Noble said in November that quarterly loss at the Nook division increased on raised spending on its e-readers and tablets to keep pace with larger rivals Amazon.com Inc and Apple Inc. The bookseller also said on Friday that sales in the crucial holiday season will come in below expectations, based on preliminary results and current sales trends.
