NBC is pulling the plug on Kings airings on Sunday night, opting instead to air Dateline. Kings episodes will be burned off on Saturday nights at 8pm beginning April 18. Given the numbers, which were already not good, and on the trend of getting worse, it's hardly a surprise.
From James Hibberd:
Sunday's Kings episode was seen by 3.6 million viewers and received a 1.1 rating among adults 18-49. Yet Dateline had a 1.5 rating in its half hour leading into Kings. NBC suspects an expanded Dateline will provide a better lead-in for 9 p.m.'s Celebrity Apprentice, which has seen some audience erosion in recent weeks that might be attributed to Kings.
