I'd pay for this: Netflix for publications
Monthly fee for a quota of articles but with access to multiple newspapers and publications.
In a time of subscriptions why not? Price per article could be calculated as SUBSCRIPTION / AVG. NUMBER OF ARTICLES READ BY A SUBSCRIBER to get the price per article for each publication. Following that, you take the costliest one in the bundle and multiply that by the number of articles that the bundle includes.
I imaged there being “bundles”, for instance a news bundle would include the Washington Post, NYT, Wallstreet Journal, etc.
