Many TV networks emphasize their slate of new series during upfront presentations, but National Geographic Channel made sure to play up its returning programs with equal zest.

The network, a joint venture of 21st Century Fox’s Fox Network and National Geographic, debuted six of the top ten series in its history, said Howard T. Owens, the network’s president. That stands in contrast to the network two or so years ago, he said, when the network had few signature franchises or familiar faces.

Nat Geo will boast ten returning series, along with six new series and a slate of five events or specials.

Returning series are: “Brain Games,” “None of the Above,” “Alaska State Troopers,” “Building Wild,” “Drugs Inc.,” “The Legend of Mick Dodge,” “Life Below Zero,” “Life Below Zero: The Thaw,” “Ultimate Survival Alaska” and “Wicked Tuna.”

New series are:

“Crowd Control” from Tigress Productions. Show uses a series of fun experiments to try to change social behavior. If staircases looked like pianos, would more people climb them?

“You Can’t Lick Your Elbow,” from Authentic Entertainment. Host and “NFL Today” analyst Tony Gonzalez teaches viewers “body hacks” that let viewers hold their breath for four minutes, see in the dark or clear nasal passages with the touch of a finger.

“Cabin Fever,” from Stiletto Television. Host Nate Heim turn timber into the stuff of dreams by building mountaintop mansions and rustic hideaways.

“Meat Heads,” from Relativity Television. Chef Eric Greenspan takes viewers on a carnivorous tour of America, seeking out everything from ostrich to gator.

“The Primitives,” from National Geographic Television. A look at families who live as they might have in the past, relying on the land to battle the elements.

“Remote Survival,” from Eyeworks USA. Individual players are dropped into the middle of nowhere, with only – no camera crews, shelter or food –  the aid of an expert talking via a two-way headset to help guide them.

The network is also set to unveil a slate of events and specials, including a two-day, four-hour “Killing Jesus,” which looks at the death of Jesus Christ; “The Great American Sleep Project,” which uses emerging science from the National Institutes of Health to expose the crucial need for sleep; and “Driving America,” the story of America’s love affair with autos.
