Big Love
9 pm/ET HBO
The 16-month layoff between seasons is practically Soprano-esque, but the payoff for another show about a redefined family is well worth the wait. Picking up right where it left off, tonight's third-season premiere finds the Henricksons being shunned by their neighbors for an upcoming block party, while Barb reconsiders adding a fourth wife. And in a nice twist, the squeaky clean Bill, feeling the economic pinch at Home Plus, is betting the farm on a spirited stab at the gambling industry. — Joe Friedrich

Desperate Housewives
9 pm/ET ABC
Since this is the series' 100th episode, it's time for reflection. The plot device to accomplish that: the death of beloved (but heretofore unknown to us) Wisteria Lane handyman Eli Scruggs (Beau Bridges), who, it seems, was around at pivotal points in the housewives' lives. And speaking of dead people, Rex Van De Camp (Steven Culp) is back tonight, and you'll be able see Mary Alice Young (Brenda Strong) as well as hear her. — Paul Droesch

United States of Tara
10 pm/ET Showtime
The protean talents of Toni Collette get put to excellent use in this edgy new cable comedy. She plays modern-day wife and mom Tara, who suffers from Dissociative Identity Disorder, which, a few psychiatric-textbook editions ago, was known as Multiple Personality Disorder. Tara's trio of "alternates" are "T," a sassy, salacious 15-year-old; Buck, a swaggering, redneck badass; and Alice, a chirpy, cheery Stepford wife. The ensemble support is excellent, and the script, from series creator and Oscar-winning screenwriter Diablo Cody (Juno), is sharp, witty, punchy and insightful. — Ray Stackhouse

Another Cinderella Story
8 pm/ET ABC Family
Teen queen Selena Gomez plays the titular fairy-tale princess in this present-day musical take on the classic fable. Her character, Mary, leads a life full of chores as she takes orders from her stepmother and stepsisters. At a masquerade ball, she dances with her high school's very own celebrity: prince of pop Joey Parker (Drew Seeley). As she runs out to make it home on time, she drops her MP3 player, and that's the only clue Joey has to finding the mystery girl with whom he's become so enamored. — Jennifer Sankowski

We Are One: The Obama Inaugural Celebration at the Lincoln Memorial
2:30 pm/ET HBO
Barack Obama's swearing in as the 44th president won't be official until Tuesday, but you can whet your appetite for the big day with this two-hour extravaganza. Among the event's performers are Stevie Wonder, Bruce Springsteen and Mary J. Blige, and those reading historical passages include Martin Luther King III, Queen Latifah and Tom Hanks. And, much like the inauguration's billing as the most open and inclusive in history, the network will make the special available to non-HBO cable subscribers. — Joe Friedrich

NFC Championship
3 pm/ET Fox
Go ahead — try and tell someone that you picked these two teams to end up in the NFC title game. Only a series of games ending the right way on the last day of the season allowed Philadelphia into the postseason, while Arizona dropped their penultimate regular-season game 47-7 and collected six of their nine wins against sub-.500 teams in their division. — Dave Roeder

AFC Championship
6:30 pm/ET CBS
Points will likely be at a premium in the chilly confines of Heinz Field this evening as the NFL's top two defensive teams fight for the right to go to Tampa. Pittsburgh will be going for a rare season trifecta, having already beaten Baltimore in two thrillers this season. — Dave Roeder
