KidsCo was an international children's television channel active from 2007 until 2014. It was a joint venture between Corus Entertainment, DIC Entertainment (later part of Cookie Jar Group) and NBCUniversal whose content was mainly commissioned by DIC and Corus subsidiary Nelvana. At its peak in 2011, it was available in at least 95 countries in 18 languages.

In early 2014, it was shut down by its owners, in light of NBCUniversal's acquisition of US children's network Sprout and "growing challenges in the international children's television industry". The network was based in London at the time of its closure.

KidsCo was co-founded by former BBC Radio 1 controller Paul Robinson, citing an increasing focus on older "tween" audiences and increasing vertical integration by mainstream counterparts Disney Channel, Cartoon Network and Nickelodeon, in addition to the need to reduce costs for other content producers by not adopting a traditional license fee deal.

The network, effectively a start-up, depended on funding provided in the form of a joint venture between Corus Entertainment (the owner of Nelvana), DIC Entertainment and Sparrowhawk Media Group. Subsequently, its offering was said to have included "over 3,000" half-hour episodes each of DIC and Nelvana content, with a broadcast facility made available by Sparrowhawk Media in the United States. Later in 2007, Sparrowhawk Media was purchased by media conglomerate NBCUniversal, while DIC was merged into Cookie Jar Group the following year.

Although numerous claims had been made of an imminent UK launch throughout its existence, the channel struggled to establish an official foothold there because market conditions at the time meant a launch would not be commercially viable. Plans had also been discussed for a potential expansion throughout France, Germany, Italy and Latin America, but these did not transpire. Robinson served as managing director of the network through 2011, after which he was succeeded by Hendrik McDermott.

The channel was first launched in Central and Eastern Europe on September 7, 2007. On January 1, 2008, KidsCo launched in the Philippines on SkyCable and on Showtime Arabia on March 20, 2008. In the first trimester of 2009 the channel was launched in Portugal on Optimus Clix. The channel become available also on Vodafone Casa TV platform on July 25, 2010.

On November 15, 2009, KidsCo launched on Australian platform Foxtel. That same month, it launched in Greece on Conn-x TV and in Cyprus on CytaVision. In November 2010 it additionally launched on IPTV in Greece. It launched on South African platforms TopTV on May 1, 2010 and DStv on July 12, 2010.

In May 2012, Cookie Jar's minority shares in KidsCo were bought by NBCUniversal and Corus, which saw the former obtain a controlling 51% stake while the latter increased its share to 43.8%.

On January 8, 2013, KidsCo began broadcasting from Corus Quay in Toronto, while also introducing a refreshed schedule, on-air look and website. In February 2013, as part of a joint venture with the NBC-affiliated Syfy network, it debuted a new programming block titled Syfy Kids.

On April 30, 2013, KidsCo was shut down on some Polish cable networks, and on others on May 5. It was removed from the AustriaSat platform on June 30, 2013.

In November 2013, citing "growing challenges in the international children's television industry", and the addition of the competing USA channel Sprout to NBC's portfolio due to its recent acquisition by Comcast, KidsCo announced that it would shut down in early 2014. KidsCo ceased broadcasting in Europe on December 31, 2013, followed by its feeds in Southeast Asia and Africa in February 2014. On VOO, the channel was replaced by Piwi+.
