Animal Planet was launched on October 1, 1996; it was created by Discovery Communications in cooperation with BBC Worldwide. On January 1, 1997, Animal Planet's distribution grew as a result of Advance Entertainment Corporation selling the satellite transponder slot belonging to the WWOR EMI Service (a national superstation feed of Secaucus, New Jersey/New York City's WWOR-TV, that was implemented following the 1989 passage of the Syndication Exclusivity Rights Rule by the Federal Communications Commission) to Discovery Communications, replacing the feed with Animal Planet outright.
In late 2005, as part of a multi-million dollar expansion, the National Aquarium in Baltimore opened an exhibit called "Animal Planet Australia: Wild Extreme". Animal Planet and the National Aquarium in Baltimore announced a multi-year partnership the year prior, which produced an original orientation film that gives Aquarium visitors background on the Australian area which inspired the new exhibit and a dedicated area inside the expansion where visitors can learn about Animal Planet's conservation efforts and other programming. The partnership also allowed the possibility of future productions of television programs about the National Aquarium in Baltimore's research and exhibits.
