NEW YORK — Samuel Irving “Si” Newhouse Jr., the low-profile billionaire media mogul who ran the parent company of some of the nation’s most prestigious magazines, died Sunday. He was 89.

Newhouse’s death was confirmed by his family, who said he died at his New York home.

The chairman of Conde Nast since 1975, Si Newhouse, as he was known, bought and remade The New Yorker and Details magazines and revived Vanity Fair. Other magazines in the Conde Nast stable included Vogue, Wired, Glamour, W, GQ, and Self.

The glossy titles helped set the nation’s tastes, reached millions of readers and appealed to upscale advertisers.

Associates said he simply enjoyed the magazine business and rubbing elbows with the cultural elite.
