The poet Ezra Pound (1885-1972) used "Jew York" is a letter dated October 28, 1931. "Jew York" was used more frequently since the 1970s; the full "Jew York City" is less frequently used.
A term similar to "Jew York" (Jew + New York) is "Jew World Order" (Jew + new world order). The New York (NY) Times is sometimes called the "Jew York Times," a reflection of both the Jews in New York City and the newspaper's Jewish owners.
Jesse Jackson's famous 1984 use of "Hymietown" destroyed his political presidential ambitions. "Hymie" (from the name "Hyman") is in the Historical Dictionary of American Slang, "a Jewish man or boy -- used derisively," with a first use of 1973.
Wikipedia: Jesse Jackson
Jesse Louis Jackson, Sr. (born Jesse Louis Burns; October 8, 1941) is an American civil rights activist and Baptist minister. He was a candidate for the Democratic presidential nomination in 1984 and 1988 and served as a shadow U.S. Senator for the District of Columbia from 1991 to 1997. He is the founder of the organizations that merged to form Rainbow/PUSH. Former U.S. Representative Jesse Jackson, Jr. is his eldest son. Jackson was also the host of Both Sides with Jesse Jackson on CNN from 1992 to 2000.
Relations with Jewish community
Jackson was criticized in the early 1980s for refusing to repudiate Louis Farrakhan, for his support of a Palestinian state, and for remarks made to a reporter where he referred to New York City as "Hymietown". (Hymie is a pejorative term for Jews.) Jackson ultimately acknowledged he had used the term, and said he had been wrong; however, he also said that he had considered the conversation with the reporter to be off-the-record at the time he made the remarks. Jackson apologized during a speech before national Jewish leaders in a Manchester, New Hampshire synagogue, but an enduring split between Jackson and many in the Jewish community continued at least through the 1990s.

In private conversations with reporters, (Jesse -- ed.) Jackson has referred to Jews as "Hymie" and to New York as "Hymietown."

While Mr. Farrakhan's own fiery speech on Dec. 18 in New York made no reference to his 1985 remark that Judaism was a "gutter religion," Mr. Muhammad at Kean was unsparing in attacking Jews and other whites.
Often affecting a Jewish accent or effeminate mannerisms, he sprinkled phrases like "Columbia Jew-niversity" and "Jew York City" through a rambling three-hour talk billed as "The Secret Relationship between Blacks and Jews."
Used by anti-semites to describe New York. Refers to the high Jewish population.

Some slang phrases, such as Jewboy (attested since 1796), Jew flag ('dollar bill,' 1932), Jew buggy ('a Cadillac,' 1960), and Jew York ('New York City,' 1931), are clearly meant to be contemptuous and are therefore unquestionably offensive.
