The San Diego Union Tribune recently implemented a paywall: One can only view a limited number of articles before being redirected to a Subscription Offers page.
OK, fine, I get that the UT is bleeding, and that Doug Manchester didn't purchase the paper solely to advocate his political views. But you never win fans by charging for something you used to give away freely.
What I find interesting, though, is the pricing structure. An "unlimited digital-only" subscription costs $3.50 per week. A Sunday-only paper delivery, which includes the same "unlimited digital-only" subscription, also costs $3.50 per week.
There are a number of ways of viewing this. The one I choose to take is that the UT recognizes that their content is the only thing they have of value. The Sunday paper only just pays for itself with revenue from advertising/coupons, hence it can be given away for free once you have chosen to pay for the content - it makes no difference to them either way. And the paper delivery of the rest of the week is the albatross on their neck, just costing them extra money, so you're going to have to pay up if you want that delivered.
It is at the same time mind-boggling to admit that their primary purpose for being, their namesake (the "news paper") is worthless. But in an era where so many papers have gone under for refusing to admit that fact, perhaps it is an admirable admission.
