Hulu Thursday expanded its kids-targeted content lineup with the acquisition of exclusive subscription video on demand rights to several Disney Channel, Disney Jr. and Disney XD shows.

As part of the deal, Hulu will be the exclusive subscription streaming home for all past seasons of Disney original series K.C. Undercover, as well as Dog With a Blog and Austin & Ally, said Hulu executives.

Also included in the deal were right to Disney XD titles Gravity Falls and Star vs. The Forces of Evil and Disney Junior titles Sheriff Callie’s Wild West and Henry Hugglemonster.

Overall, the deal will bring more than 500 episodes and more than 20 original movies to Hulu from Disney-ABC Television Group's suite of networks, said Hulu. 

Hulu's Disney/ABC Television Group deal follows a March deal with NBCU Television & New Media Distribution group for the streaming rights to the popular, kids-targeted Curious George series. 

"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 Craig Erwich, senior vice president and Head of Content for Hulu in a statement. “These new SVOD exclusive Disney titles mark yet another way Hulu is building an irresistible content destination for families.”

Disney Channel has ordered a fourth season of its comedy series Austin & Ally, the network announced Saturday.

The series, which stars Ross Lynch, Laura Marano, Raini Rodriguez and Calum Worthy, finished as the top series on TV among tweens in 2013, as well as the second most watched series among kids 2-11 and kids 6-11.

"The strength of this series helped make 2013 Disney Channel's highest rated year ever among Tweens, an audience that is invested in the Austin & Ally stories, and the fun they experience on a journey with the characters,” said Adam Bonnett, executive vice president of original programming for Disney Channels Worldwide. “We're looking forward to delivering many more engaging stories soon."
