"Humanitarian Crises and U.S. Foreign Policy: Somalia and the CNN Effect Reconsidered," by Steve Livingston and Todd Eachus, Political Communication, Vol. 12 (1995): pp. 413 -- 429. See also "The CNN Effect: How Much Influence Does the 24-Hour News Network Really Have on Foreign Policy," by Warren P. Strobel, American Journalism Review, May 1996, pp. 32 -- 37. Strobel confirms Gowing's finding (see note 4) and details what he calls the "five myths" of the CNN effect and its claimed impact on the making of foreign policy.
