Nickelodeon announced it has entered into an exclusive multi-territory agreement with YouTuber CKN Toys to develop original content for Nickelodeon-branded linear and digital platforms.

The deal will see Nickelodeon develop and produce an exclusive original short-form preschool series for Nick and Nick Jr.-branded platforms. The yet-to-be-named original series will be produced by Nickelodeon Australia and feature both CKN Toys’ stars Calvin and Kaison.

“CKN Toys has grown to become one of the most popular YouTube channels in the world because kids and parents alike love Calvin’s sense of fun and play, and his good-natured personality,” says Jules Borkent, executive vice president, content and network strategy, Nickelodeon International. “We’re looking forward to developing content that taps into all the things fans already love about CKN Toys and giving it a distinct Nickelodeon look and feel.”

CKN Toys features 7-year-old Calvin as he tests and unboxes the latest toy releases. The channel has more than 13 million YouTube subscribers and is one of Australia’s largest YouTube channels.

The agreement was created and brokered by CKN’s worldwide licensing agent, Haven Global, which will partner with Viacom Nickelodeon Consumer Products across multiple territories.

“Haven and Nickelodeon have been partners for decades, so it’s exciting to have the opportunity to develop a consumer products plan that embodies the fun and playful nature of CKN Toys,” says Mark Kingston, senior vice president of international, Viacom Nickelodeon Consumer Products.
