NBC offers viewers a second glance at the pilot of “Smash” (9 p.m.). The show had a healthy audience last Monday, so look for the network to offer viewers plenty of chances to get hooked. It’s certainly spent enough (reported to be more than $25 million) promoting this extravaganza, so it behooves the network to give as many folks as possible the chance to see what all the fuss is about.

I’m still not convinced that a large TV audience will care about the success or failure of a fictional Broadway show. And I don’t see why NBC doesn’t air this program at an earlier hour. At least once. “American Idol” and “Glee” regularly air at 7 p.m., and they’re clearly the show’s inspiration. Breaking in a new show at 9 p.m. is always difficult. And debuting one that’s not a familiar police procedural has proved to be nearly impossible.

Prior to “Smash,” NBC will also offer viewers a chance to catch two hours of “The Voice” (7 p.m.).

• ABC airs three episodes of “Cougar Town” (8 p.m.) in hopes of reminding viewers that the comedy returns next Tuesday.

• “Parking Wars” (8 p.m. and 8:30 p.m., A&E) returns for a fifth season, as does “Billy the Exterminator” (9 p.m., A&E).

• Cesar Millan celebrates a milestone of his own with the 150th episode of “Dog Whisperer” (7 p.m., Nat Geo Wild) dedicated to unruly dogs that come between couples and newlyweds. Just in time for Valentine’s Day.
