American Idol once again took the top two spots with adults 18-49. With total viewers, 'Idol' took the top spot and the third spot, with the premiere of Dancing with the Stars taking the second slot. Somewhat interestingly, more homes were tuned into the premiere of Dancing with the Stars than Wednesday's American Idol, but on average more people per household were watching American Idol, so it wound up with more viewers.
Modern Family was the number one scripted show with adults 18-49 (Glee was a repeat last week) and NCIS was the number one scripted show with total viewers.
