“Big Brother” (8 p.m., CBS): A winner is named — or, in this case, another loser

“Big Brother” (8 p.m., CBS): A winner is named — or, in this case, another loser gets 15 minutes of fame.

“Nazi Scrapbooks from Hell” (9 p.m., National Geographic Channel): Even the numbers are monstrous. Within a few months’ span in 1944, more than 400,000 innocent people were delivered to the Auschwitz death camp. The arrival rate each day was approximately 8,000 victims, who were exterminated with chilling efficiency by the Nazis and their collaborators.

But the unfathomable numbers of the Holocaust are supplemented by something new in “Nazi Scrapbooks from Hell” — a disturbing vision of the killers not as a collective monstrosity, but as ordinary people off the job, unwinding after their workday.

This National Geographic Channel documentary examines photographs from a scrapbook presented to the United States Holocaust Memorial Museum little more than a year ago by an anonymous donor. The album was compiled by Karl Hocker, an SS officer at the Auschwitz complex who served as the assistant to the commandant. Hocker snapped more than 100 pictures of himself and colleagues enjoying themselves at cocktail parties, sing-alongs and other afterwork activities.

The photos don’t argue against the killers’ capacity for evil. But Hocker’s album exposes them as humans, and they emerge all the more evil for it. Meanwhile, they are all the more disturbing for how, in some respects, they seem to resemble the rest of us.

This engrossing documentary also helps shed light on the shadowy Hocker, who in war trial testimony (excerpts of which are heard during the program) would deny playing any role in the executions. His own innocent-seeming photographs are subjected to computer analysis for the documentary, and help support a case that concludes otherwise.

“Celebracadabra” (noon and 9 p.m., VH1): Presto! Seven wannabe celebrity magicians will suddenly turn into just six, on the premiere of VH1’s “Celebracadabra.” Starring genuine magician Rocco Silano, this new reality series gathers the contenders at Hollywood’s Magic Castle, where they’ll attempt to learn and perform tricks as they vie for the title of Best Celebrity Magician.

Competitors include comedian Hal Sparks, singer Carnie Wilson, rapper Chris “Kid” Reid and Pussycat Doll Kimberly Wyatt.

“Carrier” (9 p.m., PBS): This compelling 10-hour documentary series is reality TV PBS style. The film chronicles daily life aboard the aircraft carrier USS Nimitz during its six-month deployment to the Persian Gulf in support of the Iraq War. Over that time, a crew of 17 filmmakers gets up close and personal with a core group among the 5,000 sailors and Marines who live beneath a major airport and sleep on the roof of a nuclear power plant. Along the way, the film captures their views on family, faith, discipline, patriotism, love and war.

“The Simpsons” (8 p.m., Fox): On “The Simpsons,” Bart joins the 4-H Club and unexpectedly falls in love with a cow. And when said bovine gets sold to a slaughterhouse, he makes an all-out effort to save it. The name of the episode? “Apocalypse Cow.”
