Rupert Murdoch is out to prove that you can serve God and mammon after all. The media tycoon’s Fox Entertainment has bought beliefnet, the largest online faith and spirituality network. …Fox said the network would give the company an online platform to distribute faith-based programming from 20th Century Fox Home Entertainment; plus products from other parts of Murdoch’s News Corporation family, including Harper Collins’s Zondervan imprint, which specialises in Christian books, and HarperOne, which publishes a selection of religious and spirituality titles.
