News Corp’s Italian DTH operation has added an additional 472,000 net new subscribers over the past 12 months. The media group is considering an initial public offering of the business, but chairman and chief executive officer Rupert Murdoch said that a decision was a long way off. Operating income rose $90 million year-on-year, producing $69 million at the end of the third quarter. However, revenue growth has been offset in part by increased programming costs arising from the growth in subscribers and the addition of new channels to the basic programming tier.
