The Fairest of Them All

Let's hear it for the what is arguably the most successful print campaign of all time, Sports Illustrated's Swimsuit Issue! 

As Dina Spector reports in Business Insider, this issue has spawned a $1Billion empire, will go to 3 million subscribers and will sell more than 1 million copies on the newsstand. On The Today Show Matt Lauer said this issue will be viewed by over 62 million.

Last year SI offered the issue on four digital platforms including a tablet edition and iPhone app.
What a great opportunity for Time, Inc. and Sports Illustrated to evaluate the impact of print vs. digital with this property. Is there a spike in digital subscriptions as well? How does the viewer experience differ between print and digital?

All I know is I won't be seeing the digital version at my dentist's office. How do you measure the value of pass along readership to your advertisers in a digital format?

As for cover model Kate Upton, congrats on your second cover. It was worth the frostbite you suffered shooting in Antarctica!
