The Washington Post announced that through a section-by-section introdution over the next month, readers of washingtonpost.com will have to provide additional information beyond the familiar triad of zip code, age and gender (this information is referred to as “ZAG”). Joining other major national newspapers including the New York Times, Los Angeles Times and the Chicago Tribune, the Post will require readers to provide “job title, a description of their primary responsibility, the size of their company and the industry in which they work.” Links to the Washington Post and Dow Jones Business News articles.
