Each winter when Fox's "American Idol" returns to the schedule, a whole slew of competing shows take hits in the ratings, and in latter February the hurt worsened when Fox doubled up "Idol" on Tuesday and Wednesdays and adds a third Thursday show.

A few programs seem immune to "Idol's" wrath. One is CBS’s “NCIS,” which targets older viewers, and there's Univision’s “La Fea Mas Bella,” which targets Hispanics.

But the majority are left hurting, and that hurt deepened last week, the week ended Feb. 25, the first with doubled up Tuesday and Wednesday shows and a Thursday "Idol" edition at 8 p.m. NBC's “The Office” and “My Name is Earl” both took slight hits--down 8 and 5 percent from the previous week--and ABC wisely chose to air a “Grey’s Anatomy” repeat in the timeslot.

Here’s a look at the five shows most hurt by “Idol” and their chances of recovering. There seems to be no common thread among them. Some are strong shows, while others were already hurting.

ABC’s “Knights of Prosperity (Wednesday 8:30 p.m.)

Last week’s episode nearly matched a series low, averaging a 1.6 in adults 18-49. ABC already moved the sitcom from 9 to 8:30 last month to get it out of the way of “Idol,” which usually airs at 9.

Considering that “Knights” also lost 27 percent from its “George Lopez” lead-in, it’s just awaiting the axe.

NBC’s “Deal or No Deal” (Wednesday 9 p.m.)

The network’s popular game show has held up against tough competition before, such as ABC’s “Grey’s” and CBS’s “CSI” on Thursdays, but last week it hit a series-low 2.1 airing opposite “Idol.”

Its Monday edition remains strong, so it’s no surprise NBC is moving “Deal” from Wednesday to Sunday next week and replacing it with “Crossing Jordan.”

CBS’s “Jericho” (Wednesday 8 p.m.)

Last fall’s pleasant surprise proved quite vulnerable to “Idol” in its winter return after a three-month hiatus, averaging a series-low 2.3. That’s a full point behind its season average.

CBS will have patience with it because “Idol” usually airs in a later timeslot. But if the low ratings continue, “Jericho” may move, possibly to Tuesdays at 10 p.m. where the network currently airs reruns.

CW’s “Veronica Mars” (Tuesday 9 p.m.)

“Veronica’s” future was already looking dim before last week’s dismal 2.3 million total viewers and retention of barely 50 percent out of lead-in “Gilmore Girls” among the network’s target 18-34s.

Now things look worse.

CBS’s “Survivor” (Thursday 8 p.m.)

Opposite a rare Thursday “Idol,” “Survivor” dipped to one of its lowest ratings ever, a 4.6, and fell 19 percent from its previous season average of 5.7.

Once “Idol” retracts back to Tuesdays and Wednesdays, “Survivor” will bounce back, but it looks increasingly vulnerable.

The show posted a 1.7 rating among 18-49s, off 32 percent from a 2.5 the previous week.
