Tune In

One Night for One Drop is a one-night-only Cirque du Soleil performance raising funds for the One Drop Foundation, a nonprofit dedicated to providing access to safe water.

Imagine a TV version of “Rip Van Winkle.” Think of him as getting hit on the noggin with his iPod back in 2004 and just waking from a 15-year nap. He might be surprised to note that “American Idol” is still on the air and so is “Project Runway.” Not to mention “Big Brother,” “Survivor” and “The Bachelor,” to name a few.

Our Rip might completely miss the fact that the past decade and a half has seen a complete revolution in the way people consume media.

He might just resume his habit of watching “Trading Spaces” (7 p.m., TLC), now entering its 10th season. Paige Davis hosts. Making the most of its retro appeal, “Spaces” asks its design team to spruce up two rooms in the spirit of the 1950s and the 1970s.

Not unlike our Rip, “Trading” took a little nap of its own and has only recently returned after a long hiatus. In many ways, it was the original “binge” show. Its old network, Discovery, would crowd the weekend hours with constant marathons of the series.

When “Project Runway” faltered during its first season, Bravo programmed it very much the same way. It turned out that viewers didn’t want to watch one “Runway” at a time, they wanted to “cocoon” (is that still a term?) all weekend and devour the show by the hours.

You can still stream episodes of “Trading Spaces”; full episodes are available at TLC.com.

While we’re on the subject of old-school reality series, “While You Were Out” (9 p.m, TV-G) also returns, airing simultaneously on HGTV and TLC.

  • “One Night for One Drop: Imagined by Cirque du Soleil” (7 p.m. Saturday, CBS) offers a spectacle with a message. An “Everyman” character takes viewers through the evolution and history of mankind, contemplating hopes and dreams for the future.

Other highlights

  • An anxious new mother joins a group for solidarity and support, only to discover that it has darker plans on its agenda in the 2019 shocker “Mommy Group Murder” (7 p.m., Lifetime, TV-14).
  • The Thunder and Warriors meet in NBA action (7:30 p.m., ABC).
  • An old kidnapper returns to form on “Ransom” (8 p.m., CBS, TV-14).

Cult choice

St. Patrick’s Day inspires many traditions. Syfy offers a marathon of “Leprechaun” movies, including “Leprechaun In the Hood” (4 p.m. Saturday, TV-14) to “Leprechaun 2” (8 p.m.). TCM takes the traditional approach, ladling out the Technicolor blarney of director John Ford’s 1952 romance “The Quiet Man” (7 p.m. Sunday, TV-PG).

Series notes

“Dateline” (7 p.m., NBC, TV-PG) ... “NBA Countdown” (7 p.m., ABC) ... The kids are all right on “MasterChef” (8 p.m., Fox, r, TV-PG) ... “48 Hours” (9 p.m., CBS) ... A vintage helping of “Saturday Night Live” (9 p.m., NBC, r, TV-14).
