Nielsen's ratings for last week confused all but the experts as the show watched by most Americans ranked fourth in the overall ratings and three shows tied for sixth place. The anomalies resulted in part from the fact that audience size changes on different nights of the week and the ratings are based on a percentage of total viewers. NBC's America's Got Talent drew an audience of 11.02 million, but it was outranked on the Nielsen list by CBS's Without a Trace, which took first place with 10.87 million viewers. CBS's CSI and CSI: Miami tied for second place with 10.57 million viewers and 10.78 million respectively. CBS shows dominated the week with an average rating of 5.0 and a 9 share. Fox placed second with a 4.0/7, just edging out NBC with a 3.9/7. ABC trailed with a 3.0/5. On cable, the second part of AMC's Broken Trail miniseries attracted 9.77 million viewers, making it by far the most-watched show on cable. Part One drew 7.7 million viewers. BET's telecast of the annual BET Awards also performed strongly as it averaged 6.64 million viewers during its three-hour production.
