Premiering Wednesday, November 3 at 9PM ET/PT, the hour-long Nanny 911 drew 8.6 million overall viewers and a 3.8/9 rating/share in the key Adults 18-49 demographic -- numbers that might be unimpressive for a NBC or CBS series but a performance that represented an impressive 46% increase over its sitcom lead-ins on the struggling Fox network.
Airing in a highly competitive time period versus three established hits (NBC's The West Wing, ABC's The Bachelor, and CBS's The King Of Queens) and two of the season's most critically-praised series (UPN's Kevin Hill and The WB's Jack & Bobby), Nanny 911 managed to win its time period among Adults 18-34, Women 18-34, Persons 12-34, and Teens.
Nanny 911 posted the Fox's biggest regular-scheduled entertainment ratings in the time period since August 4, 2004 and also outdelivered the network's prior season average in the time period (excluding sports) by 58% among Adults 18-49 (3.8/9 vs. 2.4/6).
Nanny 911 ranked among the six networks’ Top Twenty primetime programs (out of 112) of the week ending November 7 among Persons 12-34 (tied for 15th) and in the Top Ten in Teens (7th).
