<passage>:
S.I. "Si" Newhouse Jr. and his younger brother, Donald, control Advance Publications, one of America's largest privately held companies. (Estimate of their combined wealth: $13 billion.) Donald tends to Advance's hugely profitable newspaper, radio, and TV holdings. Si runs the less profitable but more glamorous properties. These are the 15 Condé Nast magazines, including (in descending order of fabulousness) Vogue , Vanity Fair , GQ , Condé Nast Traveler , House &amp Garden , Allure , Details , Self , Mademoiselle , and Glamour and Random House. You've forgotten to return the video your kids watched yesterday, so you have a messenger take it back to Blockbuster. Si spends $20 you save a $1.50 late fee. Then there's lunch. The magazines account for more than a quarter of daytime revenues at the Four Seasons and the Royalton. A modest lunch for two at the Royalton (no fancy wine or anything) might cost $80. But Si's generosity extends to even assistants and sub-sub-editors, dining on sushi at their desks. If you spend $10 or less on lunch, and claim you were working, Si pays. At Vogue and Vanity Fair , almost everyone has a "working lunch" every day . An editor at Allure says that "working lunches" there are limited to 10 a month. None of the 39 past and present Newhouse employees I spoke to for this story would talk on the record, for . And the nature of the subject makes it hard to separate apocrypha from the truth. Did Condé Nast pay, as sources insist it did, hundreds of thousands of dollars in back taxes on behalf of an editor who didn't bother to file tax forms? Did an editor really expense $20,000 in a weeklong trip to Paris? The people who pay the bills are not talking. But every example of excess cited here was told to me by at least one source (and usually more than one) in a position to know. Need a facial? Treat yourself and bill it to Si. This is what is called "scouting." It is also a great way to get free haircuts. To be fair, Si doesn't pay for all such treats. There is also a much-honored tradition of accepting tribute from companies that Condé Nast magazines cover. One magazine exec reportedly got so much loot last Christmas--Cuban cigars, "crates of wine," designer suits ("It was like a Spanish galleon")--that he needed three cars to cart it home. At yuletide, even midlevel fashion-mag writers and editors are inundated with "cashmere sweaters, Versace pillows, coats ..." recalls one ex- Vogue staffer wistfully. At the top of the masthead, the perks are perkier. His Si-ness (their joke, not mine) does not expect his editors in chief to actually live on their million-dollar salaries. He also gives them clothing allowances (up to $50,000 a year). He buys them cars of their choice and hires chauffeurs to drive them. He offers them low- or no-interest home loans. GQ editor Art Cooper reportedly received two $1-million loans, one for a Manhattan apartment, the other for a Connecticut farm. Tina Brown and her husband, Harold Evans, former president of Random House, reportedly just took a $2-million boost to buy a $3.7-million Manhattan house. Si's favorite courtiers lead lives of jaw-dropping privilege. When she was editor of British Vogue , Wintour commuted between London and New York--on the Concorde. Another Si confidant decided his office didn't feel right, so he hired one of the grandmasters of feng shui to rearrange it. Some editors prepare for trips by Federal Expressing their luggage to their destination. Why? "So you don't have to carry your bags. No one would be caught dead carrying a bag." Some Condé Nast parties are so ridiculous that even other Condé Nasties make fun of them. This week's New Yorker , for example, mocks a recent Vogue party in honor of food writer Jeffrey Steingarten. According to The                 New Yorker , Wintour so detested the carpet at Le Cirque 2000 that she ordered the florist to cover it with autumn leaves (handpicked, of course). The apogee of party absurdity is Vanity Fair 's sponsorship of an annual London dinner for the Serpentine Museum in Hyde Park. As one observer puts it, "Vanity Fair , an American magazine, pays more than $100,000 to a British art museum solely so that it can sponsor a dinner where Graydon Carter gets to sit next to Princess Diana." The princess was the museum's patron. Actually, paying $100,000 for face time with Princess Di may not have been a foolish investment for a magazine so dependent on peddling her image. And Condé Nast's excess has other plausible justifications as well. Some top editors may earn their perks. Vogue and GQ make millions, according to industry analysts. Vanity Fair is enjoying banner years, and while it probably hasn't made back the millions Newhouse lost in starting it up, it is certainly in the black. The                 New Yorker loses money--how much may even surpass perks as a topic of Newhouse gossip and speculation. On the other hand, The                 New Yorker is the most talked-about magazine in America, and Tina Brown is the most talked-about editor. That is worth something. Public media companies such as Time Warner (or, for that matter, Microsoft) can entice and hold journalists with stock options. Advance is private, so Newhouse uses other golden handcuffs. He runs a lifestyle prison. Top editors stay because they could never afford to live in a house as nice as the one Si's interest-free loan bought them, or to host parties as nice as the ones Si's party planners throw for them. Condé Nast's magazines are all about glamour, wealth, prestige. To uphold that image, magazine editors need to circulate at the top of New York society. But the top of New York society consists of people who make far more money than magazine editors do--investment bankers, corporate chieftains, and fashion designers. Million-dollar salaries aren't enough to mix as equals with the Trumps and Karans. Si's perks are equalizers. And they say it's not as good as it used to be. In 1992, according to Thomas Maier's biography of Newhouse, the editor of Self held a birthday party for Si Newhouse's dog . (Owners ate caviar dogs drank Evian.) The lowliest assistants used to take car services home. But new Condé Nast CEO Steve Florio has restricted cars and catering. Editors who used to fly the Concorde now fly first-class those who used to fly first-class now fly business. Expense accounts are scrutinized. Even so, today's Condé Nast is economical only by Condé Nast standards. The belt is tighter, but it's still hand-tooled, hand-tanned, and fashioned from the finest Italian leather.
