The whole publishing industry is watching today as Rupert Murdoch's News Corp. launches their news app for the iPad called The Daily. It's an iPad-only newspaper that will be available via subscription. The press event is going on as I write this at the Guggenheim Museum, with Murdoch and Apple's vice president of Internet services sharing the stage. This has attracted attention because it's a concerted effort to translate the newspaper format to the iPad — and because in an Internet world where much content is free, this one will cost money. Publishers are watching closely to see if this is the grail that will help stem the decline of traditional media. The cost is rumored to be $0.99 per week, and Apple may be announcing a new in-app subscription service. A helpful article in PCWorld gives more detail, including the fact that The Daily will be staffed by veteran journalists.
