Discovery Channel Canada has an ownership structure different from Discovery Channel. Canadian viewers receive almost identical English-language programming to the channel that American viewers watch, but with some added Canadian content to suit the audience. Most notably, the Canadian channel carries the daily science news show Daily Planet, originally @discovery.ca, the first of its kind. Occasionally, several segments on similar topics are taken from various episodes and put together into one-hour specials that are broadcast on the original Discovery Channel. Canadian channels Discovery HD, Discovery Health, Discovery Kids, Discovery Civilization, and Animal Planet are also seen. All channels are under different ownership, with Discovery Communications having a 20% share in each.
