Kirkus Reviews, the well-respected 76-year-old bi-monthly collection of book analysis, is being shuttered by its parent company, Nielsen Business Media. As part of a reorganization, the company will also shutter the 108-year-old Editor & Publisher — a monthly review of the newspaper business that was well read throughout the industry and launched many careers. Nielsen Business Media will also sell off eight other brands, including Adweek, Mediaweek, Backstage, Billboard, and The Hollywood Reporter. The new company e5 Global Media Holdings purchased those titles and several other Nielsen properties. "As a result of these decisions, many of our friends and colleagues within these businesses will be leaving the company or will begin to transition to the new ownership immediately," wrote Nielsen president Greg Ferrar in a letter to the company today. "The transition is expected to be complete by the end of the year."
