Ratings Chart Attack!

Waltzing into one of the lowest-rated times of the year (right before Independence Day), ABC’s “Dance Machine” made little splash during its Friday premiere, placing last in its time slot and tying for the lowest-rated show of the night.

“Machine” racked up a 1.0/4 in the 18- to 49-year-old demo, according to preliminary Nielsen data.

“Duel” tied that rating and “20/20” ended the night with a 1.3/4, down 19% from its last showing two weeks earlier. ABC finished Friday in fifth place with a 1.1 rating/4 share.

NBC placed first for the night with a 1.5 rating/5 share, bolstered by a new “Dateline” (1.6/6), off a tick from the previous week.

The CW, with a 1.4 rating/5 share, took second thanks to an on-par “Smackdown” (1.4/5). Fox and CBS tied for third with a 1.2 rating/5 share.

Fox’s cop block on Saturday gave it the win with a 1.6 rating/6 share. NBC’s 1.0 rating/4 share was good for second, ABC took third with a 0.9 rating/3 share and CBS was fourth with a 0.8 rating/3 share.

On Sunday, Olympic track and field trials (1.6/5) and a new “Dateline” (2.2/6) boosted NBC to a win with a 1.9 rating/6 share. Repeats dominated the rest of the schedule, as ABC was second with a 1.6 rating/5 share, Fox placed third with a 1.5/5 and CBS took fourth with a 1.4/4.

CBS did air a new episode of “Million Dollar Password” (1.7/5), up two-tenths of a percentage point from the previous week. CBS ordered six more episodes of “Password” last week.

The CW was fifth with a 0.3 rating/1 share.
