WSJ.com is Free Today; Thank Sprint

Could this be the wave of the future? As newspapers go to paid Web models, allowing sponsors to lift the pay wall for a day, or a week, or longer?

But, of course, if you click on the Sprint ad, it takes you not to a Sprint page but to a page where you can subscribe to the Journal at a discount.

Is The New York Times watching?
