"A compilation of highlights and clips from past programs of the National Geographic televised documentaries, marking the 30-year anniversary of the Society's documentary production. From the very first National Geographic special in 1963, which followed a team of Americans as they ascended Mt. Everest, content ranges from wilderness to cultural exploration. Through these programs, National Geographic offered a broad variety of sights and perspectives which were previously unknown to the average viewing public. Still bearing historical value, examples include segments from the films that helped promote and popularize such issues as species and habitat protection and the works of Dr. Louis Leakey, Jacques Cousteau, Dian Fossey, and Jane Goodall."@en . . . . .
