Fast National ratings for Monday, May 14, 2012.
 
NBC was so excited about Howard Stern's debut as judge on "America's Got Talent" that the network moved the start of the summer favorite into May sweeps. The result was a premiere that came in well below last year's numbers, but still performed well against stronger-than-summer competition.
 
Howard Stern aside, ABC still won Monday overall thanks to "Dancing with the Stars," while CBS captured the night among young viewers with the "How I Met Your Mother" finale and a strong "Hawaii Five-0" finale.
