Oceania is a region centered on the islands of the tropical Pacific Ocean. Opinions of what constitutes Oceania range from the coral atolls and volcanic islands of the South Pacific (ethnologically divided into the subregions of Melanesia, Micronesia, and Polynesia) to the entire insular region between Asia and the Americas, including Australasia and the Malay Archipelago. The term is sometimes used more specifically to denote a continent comprising Australia and proximate islands, or biogeographically as a synonym for either the Australasian ecozone (Wallacea and Australasia) or the Pacific ecozone (Melanesia, Polynesia, and Micronesia apart either from New Zealand or from mainland New Guinea).

The term was coined as Océanie ca. 1812 by geographer Conrad Malte-Brun. The word Océanie derives from the Greek word ὠκεανός (ōkeanós), ocean.

Geopolitical Oceania

Oceania was originally conceived as the lands of the Pacific Ocean, stretching from the Straits of Malacca to the coast of the Americas. It comprised four regions: Polynesia, Micronesia, Malaysia (now called the Malay Archipelago), and Melanesia (now called Australasia). Included are parts of three geological continents, Eurasia, Australia, and Zealandia, as well the non-continental volcanic islands of the Philippines, Wallacea, and the open Pacific. It extends to Sumatra in the west, the Bonin Islands in the northwest, the Hawaiian Islands in the northeast, Rapa Nui and Sala y Gómez Island in the east, and Macquarie Island in the south, but excludes Taiwan, the Japanese Archipelago (including the Ryukyu Islands), and Aleutian Islands of the margins of Asia.

Mary Hart (born November 8, 1950) is an American television personality and was the long-running host of the syndicated gossip and entertainment round-up program Entertainment Tonight from 1982 to 2011, which is the longest running entertainment magazine show of all time.^{[citation needed]}

Mary Hart was born Mary Johanna Harum in Madison, South Dakota and lived in Sioux Falls, South Dakota, as well as in Denmark, as a child and teenager. She speaks both Danish and Swedish fluently. Hart competed in the Miss America pageant in 1970 as Miss South Dakota, and finished in the top ten. Two years later, Hart graduated from Augustana College in Sioux Falls and while teaching English at school she also produced and anchored her own talk show on KSFY-TV, the local ABC affiliate. Also as a young adult Mary worked at JayCee Camp for the Exceptional (Handicapped, at that time) during the summer.

Hart began her full-time television career at KMTV in Omaha, Nebraska. In 1976, she went to KTVY (now KFOR-TV) in Oklahoma City, where she co-hosted a show with Danny Williams called Dannysday. She also was a sales representative for a school yearbook company. Determined to leave journalism behind, she moved to the Los Angeles neighborhood of Westwood in 1979 with $10,000 in the bank. Hart landed a small role on the soap opera Days of our Lives, as well as some TV commercials. Almost broke, she became a co-host on the Los Angeles version of the syndicated PM Magazine. That led to a job in 1981 as co-host of Regis Philbin's first national talk show on NBC. When that show was canceled four months later, Entertainment Tonight interviewed her about what it felt like to be canceled. The day after the interview, she was hired as an ET correspondent. Thirteen weeks later, she was named the show's co-host, along with Ron Hendren.
