News Corp's Chief Digital Officer Jon Miller has announced his intention to depart News Corp. Miller will remain as adviser to CEO Rupert Murdoch, COO Chase Carey, and deputy COO James Murdoch until September 2013. The departure precedes a set of business transactions that will split the company into an entertainment company, and a publishing arm that includes the Wall Street Journal in both print and digital form, a very different scenario than when Miller was hired to drive its technology and online initiatives.
