Nate the greatest writes "Microsoft has already sunk $600 million into Nook Media, the ebook division spun off from Barnes & Noble in 2012, but I guess that's not enough for the Redmond tech giant: news broke today that they have a third ebook effort in the works. A new job listing discovered by the Chinese tech blog LiveSino has revealed that Microsoft is hiring an ebook developer to work on 'a groundbreaking interactive reading app on Windows, which incorporates books, magazines, and comics.' The position was posted by the Xbox Music, Video, and Reading unit, which had already released two apps for Windows 8 (video, music) and is clearly going for a trifecta. This new app shows all the signs of being completely unrelated to the Office Reader app, which leaked last year. That app reportedly focused more on PDFs, textbooks, and office docs, while the 'Xbox Reading' app mentions magazines and digital comics."
