Amazon.com, Inc. and Showtime have taken the first tentative step into the wild, unknown world of advertisements and digital books.

In a new partnership, the cable network will offer Kindle readers the summer-long opportunity to download a free copy of the first script from Showtime's new show, "Nurse Jackie." According to Ad Age, the unique deal could forge more relationships between television and this new digital medium, paving the way for more scripts, tie-ins, and other text-based promotions on the Kindle.

Here's more from Jon Haber, U.S. director of Ignition Factory, the "media shop" used by Showtime: "Nobody has figured out what the future ad model for a device like the Kindle is going to be ... [this] is the first step in figuring out how marketers can use this platform and provide some value to consumers from a content standpoint while finding a way to raise awareness and buzz about a product, or in this case a TV show."
