Nickelodeon revealed a roster of new series coming to the network this year and beyond in its annual upfront presentation in New York City Wednesday.

In addition to showcasing its 2015-2016 content slate, the network also debuted the new preschool subscription TV service "Noggin," announced a new, consolidated marketing services division, previewed the new SpongeBob SquarePants Broadway musical currently in development and unveiled potential spin-offs for the Teenage Mutant Ninja Turtles brand.

Featuring both long and short-form Nickelodeon content for preschoolers, "Noggin" is designed to complement the "Nick Jr." TV everywhere app.

Among the shows available on "Noggin" at launch will be "Blue's Clues," "Little Bear, "Pocoyo" and "The Upside Down Show." The app will also feature games, music videos, activities and educational videos, with new content being added regularly.

Launching on the Apple App Store March 5, the paid service will be ad-free and will cost $5.99 a month. Nickelodeon is in discussions with other distributers to potentially offer "Noggin" as a premium add-on, as well.

"We are reintroducing the Noggin name with this new mobile service because of its built-in equity with moms as a signal of the high-quality preschool content that will be curated for it," says Cyma Zarghami, president, Viacom Kids and Family.

(The Noggin name was first used by Nickelodeon for a U.S. cable channel from 2002 to 2007 that featured Nick Jr. characters and was focused on educational content.)

The company also announced its new integrated marketing and creative content service, Nickelodeon Inside Out Solutions. The collaborative service aims to connect partners to Nickelodeon's platforms and characters, and makes available the company's audience expertise, creativity, advertising solutions and branded-entertainment opportunities.

Pam Kaufman, president of consumer products, highlighted the forthcoming toy line for "Blaze and the Monster Machines," anchored by licensee Fisher-Price.

Content was the focus of the bulk of the presentation though, with the network highlighting a host of new series and development projects. Among the projects that were showcased were:

Nickelodeon also announced that it will air more than 600 episodes of new series and returning favorites in the 2015-16 season. Among the new series this season are "School of Rock," a live-action show based on the movie, "Harvey Beaks," an animated show about a good kid who has never broken the rules and his two trouble-making best friends, "Shimmer and Shine," an animated preschool series about twin genies-in-training, and "Pig Goat Banana Cricket," which follows four friends on a series of surreal adventures.

The company also highlighted its ongoing Nickelodeon Sports initiative for off-channel activations and marketing partnerships with sports leagues including NFL, NBA, MLS, NHL and NASCAR.
