I subscribe to four American news weekly magazines: Time, Newsweek, US News & World Report, and The Week. This week, two of the four — Time and US News — both had the exact same picture on the cover (an American soldier in Fallujah). The Week featured the same picture on page 4 — its most prominent news page. Only Newsweek had the foresight not to publish the same photo.
The photo is an AP photo — so it is shareable by all outlets — but it shows the lack of market differentiation in the magazine news business.
