Overview
WDSU is a television station in New Orleans, Louisiana, affiliated with NBC and owned by Hearst Television. The station broadcasts on virtual channel 6 and operates from studios on Howard Avenue in New Orleans's Central Business District, while its primary transmission facilities are located in Chalmette, Louisiana. Its service area centers on the New Orleans market and includes communities across southeastern Louisiana and the nearby Gulf Coast. WDSU began broadcasting on December 18, 1948, becoming the first television station in Louisiana, the first in New Orleans, the first on the Gulf Coast, and one of the earliest stations in the United States. It was established by New Orleans businessman Edgar B. Stern Jr., who had acquired the WDSU radio stations and inherited the television construction permit associated with that purchase. The television station adopted the radio operation's long-standing relationship with NBC and has remained a primary NBC affiliate throughout its history. During its early years, WDSU carried selected programming from CBS, ABC, and the DuMont Television Network in addition to NBC material. As competing stations entered the New Orleans market and network affiliations became more structured, WDSU gradually became an exclusive NBC outlet. The station developed an unusually strong local identity through news, public-affairs programming, live coverage of Mardi Gras and the Sugar Bowl, statewide election reporting, and early hurricane coverage. Its technical initiatives included color broadcasting in 1955, a mobile news unit, an early Doppler weather radar system, and an international relay of NBC's Today program from Bimini. WDSU was a major New Orleans ratings leader for more than two decades. Its studios moved from the Hibernia Bank Building to the Brulatour Mansion in the French Quarter in 1950, and later to the Howard Avenue facility opened in 1996. The station's local programming also helped launch the broadcasting career of Dick Van Dyke, who worked on-air in several roles during the 1950s. Ownership changed several times: Royal Street Corporation merged with Cosmos Broadcasting in 1972; Cosmos sold the station to Pulitzer in 1989; and Pulitzer's television division was acquired by Hearst-Argyle Television in 1999. Hearst-Argyle later became Hearst Television. WDSU's news operation remains central to its brand. The station produces local morning, daytime, evening, and weekend newscasts and maintains severe-weather and hurricane coverage capabilities. It also has a content relationship with Cumulus Media radio stations in the New Orleans area, allowing broadcast audio to be shared during major storms. WDSU's news audience historically ranked first in the market, although WWL-TV became the dominant New Orleans station in the 1980s and WVUE later became a significant competitor. WDSU has nevertheless continued to compete through local reporting, weather information, breaking-news coverage, and NBC network programming. Hurricane response has been a defining part of the station's modern history. During Hurricane Katrina in 2005, WDSU moved its operations to sister station WAPT in Jackson, Mississippi, while some programming and weather resources also came from WESH in Orlando. The New Orleans facility largely survived, but the station's analog and digital transmitters were destroyed. WDSU used temporary arrangements involving WPXL-TV and other partner facilities, restored reduced-power analog service in October 2005, restored digital service in 2007, and completed replacement of its transmitter building with a more elevated, hurricane-resistant structure in 2008. During Hurricane Gustav in 2008, WDSU provided five consecutive days of continuous coverage, with assistance from Hearst stations and distribution through DirecTV, C-SPAN2, radio partners, and online streaming. The station generally clears the full NBC schedule, with exceptions when extended local coverage displaces regular programming. It has also carried selected New Orleans Saints games through NBC and ESPN-related arrangements, and its sports and special-event history includes local coverage of Super Bowls played in New Orleans. WDSU continues to combine network programming with local news, weather, community information, digital publishing, and emergency broadcasting.
History
WDSU's history began with New Orleans radio entrepreneur Edgar B. Stern Jr., who acquired the WDSU radio stations and inherited a permit to establish a television service. WDSU-TV signed on December 18, 1948, making it Louisiana's first television station and one of the earliest stations in the country. Its NBC relationship grew out of WDSU radio's affiliation with the NBC Radio Network. In its first years, the station also carried selected programs from CBS, ABC, and DuMont, reflecting the less rigid network structure of early American television. DuMont programming ended after that network ceased operations in 1956, while the arrival and development of competing New Orleans stations eventually left WDSU as an exclusively NBC-affiliated outlet. The station's original facilities were in the Hibernia Bank Building, then New Orleans's tallest building. In April 1950, the WDSU operations moved to the Brulatour Mansion on Royal Street in the French Quarter, with nearby buildings adapted for production. The transmitter remained at the Hibernia site until 1955, when it moved to a tower in Chalmette. WDSU introduced color programming in 1955 and built a reputation for technical experimentation and live production. It originated early broadcasts of the Sugar Bowl and Mardi Gras, developed extensive hurricane coverage, pioneered statewide election broadcasts in its market, and operated an early mobile newsgathering unit. It also relayed a Today broadcast from Bimini to the United States using a high-powered transmitter constructed by station engineers under special authorization. Local programming was an important part of WDSU's identity. Dick Van Dyke worked at the station in the 1950s as a comedian, announcer, host, and contributor to its noon programming. Other notable local programs included Midday, the movie showcase 3:00 Money Movie, and the character-based science and comedy program Morgus the Magnificent. WDSU remained New Orleans's ratings leader for more than twenty-five years, with its local news operation receiving recognition as an early innovator. In January 1972, the Royal Street Corporation merged with Cosmos Broadcasting in a transaction valued at $17 million. Cosmos sold the associated radio stations to comply with ownership restrictions and placed greater emphasis on WDSU's established news operation. By the early 1980s, WWL-TV had overtaken WDSU as the market's overall ratings leader, while WVUE later became another strong competitor. WDSU continued to invest in technology and production, including construction of the first functioning television studio at the 1984 World's Fair in New Orleans and conversion to stereo NBC programming in 1986. Cosmos sold WDSU to Pulitzer in 1989. The station dropped the television suffix from its call sign in 1993 and moved into its current Howard Avenue facility in March 1996. During the 1990s it became the first New Orleans station to operate its own Doppler weather radar system, branded Super Doppler 6000. Pulitzer sold its television division to Hearst-Argyle Television in 1999 for $1.8 billion; Hearst-Argyle subsequently became Hearst Television. Hurricane Katrina severely disrupted WDSU's technical infrastructure in 2005. Although the Howard Avenue building sustained relatively limited damage, both analog and digital transmitters were destroyed. Staff relocated to WAPT in Jackson, Mississippi, with additional support from WESH in Orlando. WDSU temporarily used other stations' facilities, restored reduced-power analog broadcasting in October 2005, restored its digital service in 2007, and completed a strengthened transmitter building in 2008. Later that year, the station mounted a five-day multiplatform response to Hurricane Gustav, supported by Hearst sister stations, radio partners, satellite distribution, and online streaming. Since 2009, WDSU has generally used its call sign as its primary verbal brand while retaining the channel 6 visual identity. The NBC peacock was incorporated into the station logo in 2015. Today, WDSU remains an active NBC affiliate whose principal differentiators are local journalism, weather coverage, emergency communications, community reporting, and access to NBC network entertainment and sports.
