After months of improving security in Iraq, the big network morning shows on Friday cited one horrific suicide bombing as proof that “mayhem and misery are back in Baghdad,” as CBS correspondent Mark Strassmann put it. But over the last five months, the broadcast networks have consistently reduced their coverage of Iraq, as if the story of American success in Iraq is less worthy of attention than their old mantra of American failure in Iraq.

Media Research Center analysts tracked all coverage of the Iraq war on the ABC, CBS and NBC evening newscasts from September 1 through January 31, and we documented a steady decline in TV coverage of Iraq that has coincided with the improving situation in Iraq. Back in September, the three evening newscasts together broadcast 178 stories about the war in Iraq; in January, that number fell to just 47, a nearly fourfold decrease. (See chart.)
