In 2005, we moved the publishing of new Berenstain Bears titles from Random House to HarperCollins. Zondervan, a major religious publisher, was part of HarperCollins. Because of his own faith, Mike Berenstain was interested in creating children’s books on spiritual themes. Stan, Jan & Mike were aware that the Berenstain Bears had always been popular in the religious marketplace due to their positive treatment of ethics and family life. So, they approached HarperCollins with the idea of creating a separate line of Berenstain Bears books on spiritual themes. HarperCollins agreed to this and Zondervan began publishing the Living Lights series in 2008.
