More than 2 million units of the Focus on the Family Radio Theatre “The Chronicles of Narnia” products have been sold since 1999, Focus and Tyndale House reported.

“While these outstanding audio resources have been steady sellers for Tyndale, the products enjoyed a surge of recent popularity in Tyndale's marketing campaign, which correlated with growing interest in the recently released major film, The Lion, the Witch and the Wardrobe,” said Doug Knox, Tyndale House Publishers senior vice president and publisher.

“The Chronicles of Narnia” audio dramas were recorded in London for airing on Focus on the Family Radio Theatre, and for release as audiocassettes and CDs, available through Tyndale House and Focus on the Family.
