NBC Tower

The NBC Tower is an office tower on the Near North Side of Chicago, Illinois located at 454 North Columbus Drive (455 North Cityfront Plaza is also used as a vanity address) in downtown Chicago's Magnificent Mile area. Completed in 1989, the 37-story building reaches a height of 627 feet (191 m). NBC's Chicago offices, studios, and owned-and-operated station WMAQ-TV are based in the building. At 10 o'clock on the evening of October 1, 1989, WMAQ-TV broadcast its first newscast from the new home, with the then-weeknight news team of Ron Magers, Carol Marin, John Coleman, and Mark Giangreco. Telemundo O&O WSNS-TV has also occupied the building since its purchase by NBC in 2001, and NBC's former radio properties, WKQX, and WLUP-FM, continue to maintain studios in the tower. The design, by Adrian D. Smith of Skidmore, Owings & Merrill, is in the Art Deco style and bears a marked similarity to 30 Rockefeller Plaza in New York City, which is NBC's global headquarters. The tower is further enhanced by the use of limestone piers and recessed tinted glass with granite spandrels. The building takes additional cues from the nearby landmark Tribune Tower with the use of flying buttresses. A 130-foot (40 m) broadcast tower and spire tops the skyscraper. WMAQ and WSNS have STL and satellite facilities on the roof; the STLs link to WMAQ and WSNS's transmitter facilities atop the Willis Tower.
