National Geographic (formerly National Geographic Channel; abbreviated and trademarked as Nat Geo or Nat Geo TV) is an American pay television network and flagship channel owned by the National Geographic Global Networks unit of Disney Entertainment and National Geographic Partners, a joint venture between The Walt Disney Company (73%) and the National Geographic Society (27%),[1] with the operational management handled by Disney Entertainment. The flagship channel airs non-fiction television programs produced by National Geographic and other production companies. Like History (which is 50% owned by Disney through A&E Networks) and Discovery Channel, the channel features documentaries with factual content involving nature, science, culture, and history, plus some reality and pseudo-scientific entertainment programming[citation needed]. Its primary sister network worldwide, including the United States, is Nat Geo Wild, which focuses on animal-related programming, including the popular Dog Whisperer with Cesar Millan. As of February 2015, National Geographic is available to approximately 86,144,000 pay television households (74% of households with television) in the United States.
