A couple weeks ago, reports surfaced that News Corp. was working on a new app-only publication. Even before much was known about the project, some heralded it as a "game changer" .

The Guardian ran a piece quoting him as calling them "the perfect platform" for cheap and convenient, up-to-date News Corp. content.
