Newspaper Paywalls: Here’s Why They’re Really Doing It | Cognoscenti:
For a long time, we had a deal. You paid a little bit for the  newspaper, but it was kind of a token amount.

In those days, it made sense to charge readers a little something for  the dead-tree version because it cost so damn much to produce.
