Zondervan is enjoying huge success on both the Christian and general charts with its latest top seller, The Purpose-Driven Life by Rick Warren, founding pastor of Saddleback Church in Lake Forest, Calif., one of America's largest and best-known churches. The book was published in October 2002, and sales are already over the 100,000 mark. The book is contracted for translation into 12 languages. The book's launch was supported by a national "40 Days of Purpose" campaign sponsored by Saddleback Church involving more than 1,550 churches representing all 50 states and nine countries. More than 500,000 churchgoers viewed a Purpose-Driven Life satellite simulcast on October 12, which kicked off the six-week campaign. Participants read a chapter a day (for 40 days) and heard a weekly sermon based on the material. A second "40 Days of Purpose" campaign will kick off on April 13. Part of the publisher's massive marketing campaign included an e-mail newsletter to retailers, in-store displays, a "40 Days of Purpose" radio blitz, a consumer e-mail campaign, national publicity and Web site promotions. Warren's previous book, The Purpose-Driven Church, won the ECPA's Gold Medallion Award and was named by that organization as one of the "100 Christian Books That Changed the 20th Century."
