WNUS

WNUS. This AM radio station, originally licensed as WIND, was a pioneering force in Chicago's broadcast landscape under the ownership of Westinghouse Broadcasting. For decades, it served as a flagship for all-news radio and talk radio formats, influencing the industry and launching the careers of numerous prominent broadcasters. Its evolution from a music and variety outlet to a news-talk powerhouse reflects broader trends in American broadcasting during the mid-to-late 20th century.

History

The station began broadcasting in 1940 on 1390 AM under the call letters WIND, owned by the Prairie Farmer magazine before being acquired by Westinghouse Broadcasting in 1955. In the late 1950s, Westinghouse Broadcasting repositioned the station, adopting the WNUS callsign and pioneering one of the nation's first all-news radio formats, competing directly with established players like WBBM and WMAQ. This shift was part of a larger corporate strategy seen at other Westinghouse Broadcasting properties, including KYW in Philadelphia and WBZ in Boston. Throughout the 1960s and 1970s, WNUS became a central hub for Chicago news and talk radio, covering major events like the 1968 Democratic National Convention and the political rise of Mayor Richard J. Daley. The station changed hands several times in later decades, with owners including Gannett and Evergreen Media, before its eventual decline and format changes in the 1990s.

Programming

WNUS was defined by its aggressive news radio format, featuring continuous news blocks, traffic and weather updates, and in-depth interviews. Its schedule included long-running programs like the morning drive show hosted by Wally Phillips, who later gained greater fame at WGN, and the investigative reports of Len O'Connor. The station also broadcast Chicago Bears football games for a period and was an early adopter of call-in talk radio segments, fostering debate on local politics and national issues. Special coverage of events such as Election Day returns and Chicago City Council meetings solidified its reputation for comprehensive local journalism, while syndicated content from figures like Larry King supplemented its original reporting.

Technical specifications

For most of its history, WNUS transmitted with 5,000 watts of power from studios located in the Merchandise Mart and later at 360 North Michigan Avenue. It broadcast on 1390 kilohertz, a clear-channel frequency shared with other stations under North American Regional Broadcasting Agreement rules, which limited its nighttime coverage area due to skywave interference from Class A stations like WRRC in Cincinnati. The station utilized directional antenna systems to maximize its signal within the Chicago metropolitan area and protect other stations on the frequency. Its technical operations were considered state-of-the-art, particularly during its peak under Westinghouse Broadcasting, which invested heavily in broadcast engineering and studio facilities.

Notable alumni

The station served as a career launchpad for many influential figures in American media. Legendary broadcaster Paul Harvey worked at the station early in his career before moving to the ABC Radio Network. Walter Jacobson, who later became a famed anchor at WBBM-TV, began his journalism career at WNUS. Talk show host and commentator Rush Limbaugh also had an early stint at the station. Other notable alumni include news director Robert Feder, television anchor Allison Rosati, and sportscaster Tim Weigel. The demanding, fast-paced environment of the all-news format honed the skills of these individuals, who went on to shape broadcast journalism at major networks like CBS, NBC, and Fox News.

Impact and legacy

WNUS is remembered as a critical innovator in the all-news radio format, proving its viability in a major market like Chicago and influencing the programming strategies of countless stations nationwide. Its commitment to local news and public affairs programming set a high standard for community service in broadcasting. The station's model demonstrated the commercial potential of talk radio, paving the way for the format's explosive growth in the 1980s and 1990s on stations like WLS and WGN. While the WNUS call letters are no longer in use in Chicago, its legacy endures in the careers it launched and its role in transitioning AM radio from a music radio medium to a primary source for news and conversation, a shift that reshaped the American media landscape.
