Microsoft announced that it discontinues its Microsoft Reader e-book service.

New e-books in its LIT format will be discontinued on November 8, and the app itself will be unavailable effective August 30, 2012, although existing customers will still be able to access it, ReadWriteWeb reported.

Reader has been around since 2000, long before the e-ink displays became commercially available. The format was intended for PCs and later extended to Windows-powered mobile devices. It uses Microsoft's ClearType rendering technology to improve reading on small screens.

The upcoming Windows 8 will offer a range of dramatic interface improvements that could support a great reading experience on Windows tablets, but with Amazon and Apple running the game as far as content, it's no surprise that Microsoft's dedicated e-book format has been shown the door.
