CBS won Monday night thanks to its comedy block and “CSI Miami,” while on NBC “Studio 60 on the Sunset Strip” sank to a new series low.

President’s Day weekend wasn’t kind to reality programming either, with CBS’s “Amazing Race” having its worst premiere to date and NBC’s “Grease: You’re The One That I Want” and “The Apprentice” sinking to series lows.

“Studio 60’s” weak performance was the show’s last scheduled airing; as scheduled, NBC replaces it next week with “The Black Donnellys.”

CBS led Monday with “How I Met Your Mother” (3.5), “The Class” (3.3), “Two and a Half Men” (5.3), “Rules of Engagement” (4.9) and “CSI: Miami” (5.9).

NBC was second with “Deal or No Deal” (4.8), “Heroes” (6.0), then “Studio 60” (2.6).

Fox was a close third with “Prison Break” (3.9) and “24” (5.0), both down slightly.

ABC was third with “Wife Swap” matching its season high (3.7), followed by on-par editions of “Supernanny” (3.5) and “What About Brian” (2.7).

Reality Slump

On Sunday, “The Amazing Race: All Stars” fell 27 percent from its premiere last February and 14 percent from its premiere in September to a 3.0, according to preliminary Nielsen Media Research reports. The debut was up against NBC’s “Grease” which sank to a 1.9, followed by “The Apprentice” which was down to a 2.3.

Meanwhile ABC ruled the night with “America’s Funniest” (2.8), “Extreme Makeover” (5.4), “Desperate Housewives” (6.9) and “Brothers & Sisters” (4.6). The lineup was roughly on par, with “Brothers” up 5 percent from last week.

Fox was second due to a NASCAR overrun boosting both its average rating and giving a strong lead in to its comedy block, which were all up over last week’s season-low deliveries. “The Simpsons” earned a 4.3, “King of the Hill” a 3.5, “Family Guy” a 4.3 and “American Dad” a 3.5.

CBS was third with “60 Minutes” (1.8), the aforementioned “Race,” “Cold Case” (3.0) and “Without a Trace” (2.9).

NBC was fourth with “Deal or No Deal” (2.4), “Grease” and “Apprentice,” then “Crossing Jordon” (2.5).

On The CW, the series finale of “Reba” earned a 1.5, followed by “7th Heaven” (1.2).
