The Economist's Experiment
Then apparently, they came to believe that the profit maximizing policy would be to have free access for everyone to all articles, in the hope that the larger number of visitors would generate enough additional advertising revenue that it would compensate (or even more than compensate) the loss in subcription fee revenue caused by some readers deciding that they don't need a subscription if they can read it for free on the Internet.
But now The Economist has made a 180 degree reversal and will not allow any print article to be read by non-subscribers, an even more restrictive policy than before.
This clearly indicates that the increase in advertising revenue was nowhere near enough to cover for the loss in subscription revenue. It remains to be seen however whether this complete reversal will also mean a reversal in the downward trend for revenue. The New York Times failed "Times Select" experiment wasn't exatly succesful either.
