Breakthrough Entertainment has sold the worldwide TV rights for its upcoming live action tween comedy Grounded to Nickelodeon, for airing on its global network of channels.

Breakthrough will produce an initial 26 episodes of the half hour comedy  with Los Angeles-based Hartbreak Films, with production set to start in Toronto in summer 2012.

Grounded portrays two teenaged Greek goddesses who, after misbehaving, are cast out of Mount Olympus and told to work in their mortal Uncle Gus’ Pita Palace in a suburban mall as punishment.

Nickelodeon channels will debut the tween comedy in Spring 2013.

Rival producer Shaftesbury Films also announced at MIPTV that is is reteaming with veteran TV producer Bruce Kalish on Fade In, a tween series being developed out of its Los Angeles office, Shaftesbury U.S.

The half-hour series focuses on 15-year-old aspiring filmmaker Ryan Spencer as he copes with his eccentric family and friends by documenting his life and experiences on camera.

No word on casting.

Kalish will also work again with Shaftesbury U.S. co-heads Maggie Murphy and Tom Mazza after they collaborated on the Mudpit hybrid kids series for Cookie Jar Entertainment.

Kalish also created and executive produced the Disney XD series Aaron Stone (pictured), which was shot in Toronto by Shaftesbury Films.

Also in Cannes, NBC Universal’s UK pay-TV platform Universal Channel has acquired the Canadian cop drama King for a British debut this month.

The Amy Price-Francis-starrer from Indian Grove Productions is now in its second season on Showcase.
