This idea will save the Chicago Tribune
(Disclaimer, this is just an idea. This is not for real)
Every newspaper has a unique number printed in it. At night on the 9pm WGN News they announce the winning number with a $1,000 prize. People love to gamble. People love the chance to maybe win something. And you get that chance EVERY DAY with a subscription. WOW. SIGN ME UP!
In the newspaper just below the game number is the claim ID. If you have the winning number, you use your claim ID to get your prize.
But what if people just go to the store, and write down a bunch of number/claim ID pairs? Easy solution. Print the number/claim ID in a different spot every day. Then every night the WGN News tells you where to look in your paper for the number. That way it gets people into different sections of the paper.
The winning number is also announced on the website. More traffic to the website!
And if you don't win, then you can enter your number/claim ID every day for the chance to win the monthly prize! Or stack up your points like Pepsi points where you can use your points to buy stuff. Where do you enter your number? On the website, of course.
And if by some chance two people enter in the same claim ID (perhaps they got it from a paper sitting on the train), then the winner must produce the actual paper to win.
