'K.C. Undercover' and 'Dog With A Blog' are among the shows coming exclusively to Hulu.

Hulu is bulking up on exclusive shows for kids through a new licensing pact with Disney-ABC Television Group.

The deal, the most expansive between the two companies to date, will give Hulu streaming rights to more than 500 episodes and 20 original movies from Disney Channel, Disney Junior and Disney XD.

As part of the agreement, Hulu will become the exclusive subscription streaming home to seven Disney shows, including Zendaya-starrer K.C. Undercover and Disney XD animated series Gravity Falls. It also has exclusive rights to all episodes of older shows Dog With a Blog and Austin & Ally. Further, Disney Junior shows Sheriff Callie's Wild West and Henry Hugglemonster will be exclusive to Hulu.

Complete seasons of all shows will be made available to Hulu subscribers later this month and subsequent seasons will be made available in their entirety after the end of each show's season.

"As our biggest content licensing agreement with the Disney brand, this deal further demonstrates our commitment to offering popular, high-quality kids programming on Hulu," said content chief Craig Erwich. "These new SVOD exclusive Disney titles mark yet another way Hulu is building an irresistible content destination for families."

Hulu has historically been less focused on kids programming than streaming competitors Netflix and Amazon, which both boast robust pipelines of original programming for children. In 2014 it released animated series The Doozers and has subsequently made a string of recent deals to bring more licensed series to its kids section, including exclusive rights to Curious George and as well as streaming rights to Nickelodeon classics like SpongeBob SquarePants and The Wild Thornberrys.

Hulu had previously pacted with Disney-ABC TV Group for Disney Junior series Doc McStuffins and Bunnytown.
