The New York Times' subscription drive, for 50% off regular prices, is a great example of presenting a newspaper's various products in a clear and easy to understand manner.
The Sail Into Summer campaign offers the following to new subscribers:
All Digital Access: unlimited access to NYTimes.com and the NYTimes tablet and smartphone apps
Today's Paper: web app with sections organized just as they are in the print edition of The Times
TimesMachine: complete digital replicas of every issue of The Times published from 1851 to 1980
I have witnessed a more aggressive and far reaching campaign on the part of the NYT to attract subscribers. In fact, the Times finds new subscribers on Facebook, where it has grown its paid subscriber base by targeting those faithful Facebook users with an innovative keyword analysis and content targeting tool called Keywee, which analyzes content and automatically finds qualified audiences that drive business results.
