The CW, a network geared to viewers barely out of kindergarten at the turn of the century, reaches back more than 40 years to broadcast “Here Comes Peter Cottontail” (7 p.m.). This animated special, produced by Rankin-Bass (“Rudolph the Red-Nosed Reindeer”), features the voices of Danny Kaye, Casey Kasem and Vincent Price.
For a more contemporary look at the Easter egg delivery business, don’t miss the 2011 animated comedy “Hop” (7:45 p.m., HBO Family), featuring the voices of James Marsden, Russell Brand and Kaley Cuoco.
• Ivy returns Sam to town on “Smash” (9 p.m., NBC). This ambitious and largely ignored melodrama moves to Saturday nights beginning April 6. For an idea of just how unwatched “Smash” has become among viewers ages 18 to 49, consider that it received a 0.7 rating in that demographic. That’s less than three-quarters of the 18-to-49 audience for NBC’s “Betty White’s Off Their Rockers,” a candid-camera show hosted by a genial nonagenarian. Ouch!
