Kids network also announces dance series

The Thursday morning Nickelodeon upfront at the Hammerstein Ballroom in New York featured Amy Poehler, touting her new co-created cartoon “The Mighty B!,” which is skedded for an April 26 launch and will include Andy Richter and SNL’s Kenan Thompson (formerly of the Nick show “Kenan and Kel”).

In addition, Nick is getting into the dance competish game: “Dance on Sunset” will feature teenage contestants and is designed to skew older than the net’s traditional pre-teen demo. Guests featured on the show will include Janet Jackson and Natasha Bedingfield, who closed out the morning’s conference with “Love Like This” and “Unwritten.”

Other offerings from the kid-centric net included a made-for-TV movie starring “Law & Order: SVU” thesp Christopher Meloni. The film, “Gym Teacher: The Movie,” will feature Amy Sedaris and Nathan Kress, who also appears on the net’s multiplatform “iCarly.”

Also at the upfront, Sony Music Label Group chairman Rob Stringer announced “One4All,” a new live-action scripted show about a boy band, produced in partnership with Sony/BMG. The show was pitched as a teen version of “Entourage,” about one boy with talent and three hangers-on trying to make the big time.

Nick prexy Cyma Zarghami also announced syndicated pickups of “That 70′s Show” for The N, and renewals of shows including “The Fairly OddParents” and “Spongebob Squarepants.”
