No 'Survivor,' it does find femme fans

CBS’ “Big Brother” has wrapped its first full week with credible ratings, as four of its five airings placed first in total viewers and some key demos — though the show is still not exhibiting any real signs of a runaway hit.

The five-night-a-week reality series, which follows the every move of 10 people attempting to co-exist in the “Big Brother” house, is performing best among women 25-54, who helped the show chalk up timeslot-winning scores each night except Tuesday (opposite ABC’s “Who Wants to Be a Millionaire”).

The show has been under a ratings microscope since its July 5 preem. While ratings are nowhere near those of the Eye’s summer smash “Survivor,” which benefits from airing just once a week, it’s provided the net with significant gains vs. last year in most of its timeslots. CBS execs remain optimistic that “Brother’s” best numbers lie ahead.

The web has skedded it for 55 more segs over the next 11 weeks, wrapping Sept. 30.

Thursday’s hourlong seg, which featured the first nominations for banishment from the house, averaged a first-place 10.97 million viewers from 8-9 p.m., according to Nielsen.

However, in adults 18-49 it fell 5 shares behind NBC’s “Friends” at 8 p.m. (5.2/19 vs. 3.8/14) before pulling ahead of the Peacock’s “Daddio” and ABC’s “Whose Line Is It Anyway” by 3 shares at 8:30 (4.5/15 vs. 3.7/12).

For the hour, “Brother” placed first in women 25-54 (5.7/17, tied with NBC) and second in adults 25-54 (4.6/15), men 25-54 (3.4/12) and adults 18-34 (3.8/14).

Eye-opening gains

Compared with the net’s showing in the 8 p.m. Thursday hour this season with “Diagnosis Murder,” “Brother” is posting gains of 44% in adults 25-54, 83% in adults 18-49 and 192% in adults 18-34.

Compared with last week’s half-hour Thursday seg (the first episode following a Wednesday preview), this week came in down 5% in viewers (10.97 million vs. 11.58) and adults 18-49 (4.2 vs. 4.4).

Preliminary Nielsen figures show Friday’s half-hour winning its slot in viewers (8.1 million), adults 18-49 (2.9/12), adults 25-54 (3.2/12) and adults 18-34 (2.6/12).

Saturday’s hour, which included a recap of the week’s events, won in total viewers (6.6 million, tied with Fox) and women 25-54 (3.1/11) while placing second to Fox in all other key demos.

In the other countries where “Big Brother” has aired, ratings have picked up once housemates were in jeopardy of being booted out. This Thursday’s “live” episode will feature the removal of the first housemate, as voted on by viewers.
