WDSU

WDSU (channel 6) is a television station in New Orleans, Louisiana, United States, affiliated with NBC and owned by Hearst Television. The station's studios are located on Howard Avenue in the city's Central Business District, and its transmitter is located on East Josephine Street in Chalmette.

The station first signed on the air on December 18, 1948. It was the first television station to sign on in the state of Louisiana, the first in the city of New Orleans, the first on the Gulf Coast, the first in the Deep South, and the 49th in the nation. It was founded by New Orleans businessman Edgar B. Stern, Jr., owner of WDSU radio (1280 AM, now WODT; and 93.3 FM, now WQUE-FM). Stern had inherited the construction permit to build the television station a few months earlier when he bought the WDSU radio stations for $750,000. The station has been a primary NBC affiliate since it signed on, owing to WDSU radio's longtime affiliation with the NBC Radio Network; however, it initially also carried programming from the three other major broadcast networks at the time: CBS, ABC, and the DuMont Television Network. It lost DuMont programming when that network ceased operations in August 1956. Even after WJMR-TV (channel 61, now Fox affiliate WVUE on channel 8) signed on in November 1953 as a primary CBS and secondary ABC affiliate, WDSU continued to "cherry-pick" a few of the higher-rated programs carried by those two networks until September 1957, when WWL-TV (channel 4) signed on as a full-time CBS affiliate. At that time, WJMR became a full-time ABC affiliate, leaving WDSU exclusively with NBC.

The radio station was originally located at the DeSoto Hotel (now the Le Pavillon Hotel) on Baronne Street; the "D" in the name stood for the DeSoto, while "S" referred to the now-defunct New Orleans States newspaper (which had maintained a news share agreement with WDSU radio that lasted for one year; in 1958, the paper merged with the New Orleans Item-Tribune, which in turn merged with the Times-Picayune in 1980) and the "U" stood for Joseph Uhalt, who founded the radio station as WCBE in 1923. WDSU-TV originally operated out of studio facilities located within the Hibernia Bank Building, the tallest building in New Orleans at the time (a plaque commemorating its distinction as the station's original broadcasting facility is located on the 14th floor of the building). The WDSU stations moved into the historic Brulatour Mansion on Royal Street in the French Quarter in April 1950; Stern had also bought other buildings near the mansion (including a lumber yard and an ice house) to construct production studios for the radio and television stations. At that point, Stern reorganized his business interests as the Royal Street Corporation. The transmitter site remained at the Hibernia Bank Building until 1955, when it moved to its tall tower in Chalmette.

In the 1950s, WDSU-TV became the springboard for the career of Dick Van Dyke, first as a single comedian and later as the emcee of a locally produced comedy program on the station; among his duties, Van Dyke had also served as a staff announcer, hosted music programs and appeared in a segment during the station's noon newscast. WDSU-TV became the first television station in the New Orleans market to telecast its programming in color in 1955. WDSU-TV was the ratings leader in New Orleans for over a quarter century, largely because of its strong commitment to coverage of local events and news. It originated the first live broadcasts of the Sugar Bowl and Mardi Gras, and was the first area station to provide extensive local hurricane coverage. The station was also the first television station in the market to provide statewide election coverage, as well as the first to utilize a mobile newsgathering unit.

WDSU-TV was also the first to originate an international broadcast, relaying a Today broadcast from Bimini to the United States in 1955, using a 300,000 watt transmitter built by WDSU-TV engineers via special permission granted to NBC by the Federal Communications Commission (FCC).

In January 1972, Royal Street merged with Columbia, South Carolina–based Cosmos Broadcasting in a $17 million deal. Cosmos decided to sell off the radio stations because the ownership of the three station properties combined would exceed ownership limits of the time set by the FCC. Cosmos eliminated much of the local flavor that had been the station's hallmark, opting to concentrate on its already strong news operation (channel 6 had been saluted by Time as a news pioneer in 1966). By the early 1980s, rival WWL-TV had overtaken WDSU as the top-rated station from sign-on to sign-off as well as in local news. WDSU has been a solid runner-up to WWL for most of the last quarter-century, although since the mid-2000s, it has had to fend off a strong challenge from a resurgent WVUE. In 1984, WDSU built the first working television studio at a World's Fair for the station's live broadcasts from the event held in New Orleans that year. On February 17, 1986, WDSU became the first NBC affiliate in Louisiana to broadcast its programs in stereo.

Cosmos sold WDSU to Pulitzer, Inc. for $47 million in 1989. Under Pulitzer, channel 6 finally dropped the "-TV" suffix from its calls in 1993, more than 20 years after it and its former radio sisters had gone their separate ways. In March 1996, the station moved into its current facility on Howard Avenue, located a few blocks from the Le Pavillon Hotel, where WDSU radio began operations in 1923. Also during the 1990s, WDSU became the first New Orleans station to operate its own Doppler weather radar system ("Super Doppler 6000"). Pulitzer sold its entire television station division, including WDSU, to Hearst-Argyle Television (predecessor to the present-day Hearst Television) in 1999 for $1.8 billion. WDSU celebrated its 60th anniversary of broadcasting on December 18, 2008.

Since 2009, WDSU has simply branded with its callsign in most verbal references, despite retaining the "channel 6" red dot logo it has used since 2000. In 2015, the NBC Peacock logo was added to the "channel 6" red dot logo.
