After graduation, he worked as a disc jockey for an obscure New York City station playing rock music. He discovered a talent for Lenny Bruce-type comedy, and developed a wide-ranging confrontational style. He migrated to FM radio stations in Detroit, Michigan and Washington, D.C., and returned to New York City in 1982 to work at an NBC-affiliated AM radio station WNBC-AM. Also working at NBC was David Letterman, who became a fan of Stern's radio show. Stern's guest appearance on Late Night with David Letterman on June 19, 1984, launched Stern into the national spotlight and gave his radio show unprecedented exposure. Stern would appear on Letterman's show many times thereafter.
Stern and his crew were fired from NBC in 1985 in response to a particularly outrageous sketch, and returned to the FM band by joining WXRK. Stern's show was syndicated nationwide in the 1990s by Infinity Broadcasting.
Athough both his parents are Jewish, Stern claims on his show to be "a half-Jew". His Hebrew name is Tzvi; his paternal grandparents, Froim and Anna (Gallar) Stern, and maternal grandparents, Sol and Esther (Reich) Schiffman, were Jews from Austria-Hungary who emigrated to America at about the same time.
On June 4, 1978, Stern married his college sweetheart, Alison Berns, at Temple Ohabei Shalom in Brookline, Massachusetts; they have three daughters. In October of 1999, Stern announced he and Alison were divorcing. Alison remarried in 2001 to David Lobosco. Stern has been dating model Beth Ostrosky since early 2000.
