Since the mid-2000s, popular children's programs have been produced for cable networks such as Nickelodeon, Disney Channel and Cartoon Network that are targeted at the demographic and only provide educational content voluntarily – in which case, it is primarily aimed at preschool-aged children and relegated to morning hours, unless incorporated full-time as part of the channel's format, as is the case with the spin-offs of the former two aforementioned networks Nick Jr. and Disney Junior – as they are not bound by the Children's Television Act's guidelines.
