'Teenage Mutant Ninja Turtles' Among 5 Nickelodeon Renewals

The pickups come as the Viacom kids-focused cable network has yet to announce a permanent replacement for president Cyma Zarghami.

Nickelodeon, in the midst of a search for a permanent replacement for programming veteran Cyma Zarghami, solidified its lineup by handing out renewals for five series Friday during its time at the Television Critics Association's summer press tour.

Returning for additional seasons are animated series Rise of the Teenage Mutant Ninja Turtles, Henry Danger, Knight Squad, The Dude Perfect Show and Hunter Street.

The pickups come as the Viacom-owned cable network is in the midst of a search to replace Zarghami, who had been with the network for more than three decades, most recently serving as president of the Nickelodeon Group.

Among the renewals are Henry Danger, the live-action series created Dan Schneider. Nickelodeon parted ways with the prolific kids programming creator in March. Henry Danger will return for its fifth season, consisting of 20 episodes. Former head writer Christopher J. Nowak is taking over for Schneider on the series. (Schneider will still be paid as creator of the series, per union rules, but is no longer involved in any capacity and will not earn exec producer payment.)

Also returning are live-action series Knight Squad (for a second season of 10 episodes), The Dude Perfect Show (season three, 15 episodes) and Hunter Street (season three, 30 episodes.)

In the midst of its executive search, Viacom chief operating officer Sarah Levy is filling in as president of the Nickelodeon Group.

Nickelodeon continues to rank as the No. 1 network for kids though its ratings — like that of its competitors — have tumbled in the past year amid competition in the space from streaming giant Netflix.
