That seems pretty clear from the July issue of Vanity Fair, guest-edited by U2's Bono and entered dedicated to issues affecting the continent. It's something I make a prolonged point of in a lengthy story that will run in The Jewish Journal's philanthropy issue next week.
Two major Christian magazines also thought African development -- "Health and Wealth" and "The (Prosperity) Gospel" -- was big news this month and published these side-by-side dueling covers.
The Christianity Today issue came out first (I have a story inside it about whether Christian's can stop sinning), and having the same cover focus is incredibly common for the national newsweeklies Time and Newsweek. But usually it would take an event the magnitude of Billy Graham dying or Christ returning to generate such like-mindedness in among Christians.
