NEW YORK -- Newspaper baron William Randolph Hearst wanted to make a splash with his New York headquarters in 1926, so he hired Joseph Urban, an Austrian emigre with a flair for the theatrical.
The veteran set designer had worked for the Metropolitan Opera, the Ziegfeld Follies and Hearst's Cosmopolitan Productions movie studio.
The result was the International Magazine Building, an imposing limestone box on 8th Avenue that might have been mistaken for a bank save for the telltale sculptures representing tragedy, industry, music and printing - and gigantic, bedpost-like columns rising from the sixth story.
It's the kind of audacious style that's still in vogue in Midtown today, and for good reason. The area is the nerve center for the nation's media, a place where buildings aim for boldness to mirror the creativity inside.
A 40-block swath on Manhattan's West Side, the corridor houses the headquarters of eight of the nation's largest media and entertainment companies, key subsidiaries of others and - not coincidentally - the theater district and Times Square.
Clustering the nation's media so closely means paying the price for elite office space, which can command rents of $80 to $100 per square foot, making it some of the most expensive commercial real estate in Manhattan and the nation. But being there also means having access to talent, transportation and lunches with allies or competitors.
"In a high-return business like media that relies on intellectual capital, the last thing they'll mention is low rent," said Daniel L. Doctoroff, New York's deputy mayor for economic development.
The so-called Media Corridor runs between 8th Avenue and Avenue of the Americas (6th Avenue), and roughly from Columbus Circle south to 40th Street.
The area has long been home to major TV and radio networks, many of the biggest magazine and book publishers and the advertising industry that grew up with them.
But with the world increasingly turning digital, there were predictions that the city's media constellation would fragment.Why pay Manhattan rents, when you can do the work from anywhere and, when necessary, electronically?
"That's proven to be a complete fallacy," Doctoroff said. "People want to do things face to face."
Instead of shrinking, the media cluster has grown denser.
Some of New York's most exciting new buildings are in the Media Corridor, housing companies like Time Warner Inc., Conde Nast Publications, Hearst Corp. and - in a dramatic Renzo Piano tower set to open in the spring - the New York Times Co.
Bloomberg's much talked-about new headquarters is something of an outlier, at the site of a former department store on the Upper East Side, spectacularly repurposed by architect Cesar Pelli.
Besides being wired for digital communication from the ground up, "New buildings are more conducive to creative activity," said Mitchell L. Moss, a professor of urban policy and planning at New York University who has mapped the expansion of the Media Corridor.
Hearst - corporate parent of magazines including Cosmopolitan and Esquire, newspapers including the San Francisco Chronicle and 28 TV stations - in some ways best exemplifies the corridor's evolution.
Not only did the company stay put in New York, but it also used the International Magazine Building as a base for the new, 46-story Hearst Tower designed by the British architect Norman Foster.
From inside the lower floors of the glass-and-steel tower, Urban's surrounding limestone facade does indeed resemble a stage set.
Paul J. Luthringer, a Hearst spokesman, said the proximity of media planners and advertising companies made staying in New York a necessity, but the amenities of the building were a plus.
Situating the elevator well against a back wall instead of in the central core made it possible to provide spectacular views for nearly all 2,000 employees.
Looking a few blocks north to Columbus Circle from certain upper floors, one can spy on Time Warner chief executive Richard D. Parsons as he ducks onto the garden terrace outside his office to smoke a cigar.
When the Time Warner Center, designed by David Childs, opened nearly three years ago, Parsons called the mixed-use complex "both a showcase and a workplace." It also helps to enhance the brand of both the corporation and cable-news subsidiary CNN, whose studio there has become a tourist attraction.
The broadcast networks also are alive to the branding opportunities of the high-traffic corridor. ABC, CBS and NBC all produce their live morning shows from street-level studios that allow the public to look on and sometimes interact.
News Corp.'s Fox News runs a giant electronic news ticker along the facade of the company's headquarters at Avenue of the Americas and 48th Street. News service Reuters does the same at its nearby headquarters in the heart of Times Square.
City government helped set the stage for the Media Corridor's development by cleaning up some of the seedier aspects of Times Square without robbing it of its glitz, according to Robert D. Yaro, president of the Regional Plan Association, a nonprofit research and advocacy group. In fact, Yaro noted, a city ordinance requires buildings in Times Square to devote much of their facades to billboard space.
Foreign media companies such as Bertelsmann, Sony Corp. and Reuters Group made big commitments to the Times Square area, and local companies - Time Warner, New York Times and Hearst - later made plans to expand. Part of the draw to the West Side was that it was relatively underdeveloped. Needing new buildings, companies gravitated to the one place in Midtown Manhattan where a lot of space was available.
