WNET (channel 13), branded on-air as Thirteen (stylized in all caps as THIRTEEN), is a primary PBS member television station licensed to Newark, New Jersey, United States, serving the New York City area. Owned by The WNET Group (formerly known as the Educational Broadcasting Corporation and later as WNET.org), it is a sister station to the area's secondary PBS member, Garden City, New York–licensed WLIW (channel 21), NPR member WLIW-FM (88.3) in Southampton, and two class A stations: WMBQ-CD (channel 46), and WNDT-CD (channel 14, which shares spectrum with WNET).

WNET and WLIW share studios at One Worldwide Plaza in Midtown Manhattan with an auxiliary street-level studio in the Lincoln Center complex on Manhattan's Upper West Side; WNET's transmitter is located at One World Trade Center.

History Independent station (1948–1962) WNET commenced broadcasting on May 15, 1948, from a transmitter located atop First Mountain in West Orange, New Jersey, as WATV, a commercial television station owned by Atlantic Television, a subsidiary of Bremer Broadcasting Corporation. Frank V. Bremer, the CEO, also owned two North Jersey radio stations, WAAT (970 AM) and WAAT-FM (94.7 MHz). The three stations were based in the Mosque Theatre at 1020 Broad Street in Newark. WATV was the first of three new stations in the New York City television market to sign on the air during 1948, and was also the first independent station. One unusual daytime program, Daywatch, consisted of a camera focused on a teletypewriter printing wire service news stories, interspersed with cutaways to mechanical toys against a light music soundtrack. Another early series by the station was Stairway to Stardom (1950–1951), one of the first TV series with an African-American host. WATV's transmitter was moved to the Empire State Building in November 1953.

On October 6, 1957, Bremer Broadcasting announced it had sold its stations for $3.5 million to National Telefilm Associates (NTA), an early distributor of motion pictures for television, joining its NTA Film Network. On May 7, 1958, channel 13's call sign was changed to WNTA-TV to reflect the new ownership; the radio stations also adopted these call letters. NTA's cash resources enabled WNTA to produce a schedule of programming with greater emphasis on the people and events of New Jersey, compared to the other commercial television stations. NTA also sought to make channel 13 the center of a new commercial network, though during its run the NTA Film Network offered only one night of "in-pattern" network programming, Friday nights in 1957–58, and for most purposes WNTA served as the New York showcase for nationally syndicated programming and produced several such entries, notably the anthology drama series Play of the Week; the talk show Open End, hosted by David Susskind; children's show The Magic Clown; and a popular dance program emceed by Clay Cole. The station continued to lag behind New York's other independent stations—WNEW-TV (channel 5), WOR-TV (channel 9) and WPIX (channel 11)—in terms of audience size, and NTA incurred a large debt load. National Telefilm Associates put the WNTA stations up for sale in February 1961.

Transition (1961–1962) At least three prospective purchasers expressed interest in WNTA. The most prominent was the New York City-based group Educational Television for the Metropolitan Area (ETMA), a consortium of businesspeople, cultural leaders and educators who intended to turn channel 13 into New York City's educational station. By this time, it was obvious that the non-commercial frequency that the Federal Communications Commission (FCC) originally allocated to the city, UHF channel 25, would not be nearly adequate enough to cover a market that stretched from Fairfield County, Connecticut, in the north to Ocean County, New Jersey, in the south. Prior to 1964, when the FCC required television manufacturers to include UHF tuners in newer sets as per the All-Channel Receiver Act passed in 1961, most viewers could not view UHF stations except with an expensive converter; only a few manufacturers made sets with built-in UHF tuning. Even for those who could access UHF stations, reception was marginal even under the best conditions.

With assistance from the University of the State of New York, ETMA had attempted to purchase channel 13 and convert it into a non-commercial station in 1957, when Bremer Broadcasting first put the station on the block; this bid was later withdrawn. This time ETMA was competing with NTA founding president Ely Landau, who had formed a syndicate to buy the station after resigning from NTA; and David Susskind, who received financial backing from Paramount Pictures.

ETMA's initial bid of $4 million was rejected by NTA, but the citizens' group remained persistent. With the support and guidance of National Educational Television (NET), ETMA later received an endorsement from newly appointed FCC chairman Newton N. Minow, who established public hearings to discuss the fate of channel 13. The pendulum quickly shifted in favor of channel 13 going non-commercial, and the commercial suitors withdrew their interest.

On June 29, 1961, ETMA agreed to purchase WNTA for $6.2 million. About $2 million of that amount came from five of the city's six remaining commercial VHF stations (WPIX was the lone holdout), all of whom were pleased to see a competitor eliminated. In addition, CBS later donated a facility in Manhattan to ETMA and NET to use as a studio. The FCC approved the transfer in October, and converted channel 13's commercial license to non-commercial.

The outgoing New Jersey governor, Robert B. Meyner, addressing state lawmakers' concerns over continued programming specific to New Jersey, and fearing the FCC would move the channel 13 allocation to New York City, petitioned the United States courts of appeals on September 6, 1961, to block the sale of WNTA-TV. The court ruled in the state's favor two months later.

The unsettled deal almost caused National Telefilm Associates to reconsider its decision to sell the station altogether, and NTA made plans to go forward: WNTA-TV made a play to acquire broadcast rights for the New York Mets baseball team for its inaugural 1962 season. Faced with either consummating the transaction or seeing it canceled, ETMA settled their differences with New Jersey officials on December 4, 1961. After a few last-minute issues arose to cause further delays, the transfer became final on December 22. Later that evening, WNTA-TV signed off for the final time. ETMA and NET then went to work converting the station, which they said would return with its new educational format within three months.

Ten months later, channel 13 was ready to be reborn under new call letters, WNDT (for "New Dimensions in Television"). With Edward R. Murrow—then director of the United States Information Agency—as host of the maiden broadcast, ETMA—now the Educational Broadcasting Corporation—flipped the switch on September 16, 1962. The return of channel 13 as WNDT gave the New York City market its first educational station, and with a dial position on the coveted VHF band (in many other cities, including large ones, educational stations had to make do with UHF frequencies). New York's non-commercial UHF channel, on the other hand, signed on as WNYE-TV four-and-a-half years later in April 1967. Richard Heffner was appointed as WNDT's first general manager, serving in that position in its first year; Heffner continued to appear on channel 13 as producer and host of the public affairs program The Open Mind until his death in December 2013.

Educational/public television station (1962–present) During the transition, and after the inaugural broadcast, WNDT faced an immediate crisis. The American Federation of Television and Radio Artists (AFTRA) was concerned about the use of teachers—some of whom were union-certified performers—on non-commercial television, and how they would be compensated should their work be distributed nationally.

AFTRA called a strike on the morning of WNDT's debut. Engineers and technicians who were members of the International Brotherhood of Electrical Workers (IBEW) refused to cross the AFTRA picket line, leaving the station's management and other non-union employees to produce the three-hour inaugural broadcast. Immediately afterwards, channel 13 went off the air again, as the strike continued for nearly two weeks. The striking workers returned WNDT to the air after ten days and on September 28, the labor dispute was settled. However, the station's financial resources were drained, requiring an infusion of cash from the Ford Foundation to help keep the station running.

NET originally wanted to merge its operations with WNDT, which would have given the station a direct line of funding as well as make channel 13 NET's flagship station. The Ford Foundation, which supported both groups, stopped the proposed mergers on at least two different occasions in 1962 and 1965.

Events that began in 1967 led the Ford Foundation to change its stance and push for a WNDT-NET merger. The newly formed Corporation for Public Broadcasting (CPB) (created by an act of the United States Congress) initially supported NET's network role, while providing government funding for programming. But that move was followed two years later by the establishment of the Public Broadcasting Service as the CPB's own distribution system—which was a direct threat to NET's territory. It has been intimated that the CPB's creation was an attempt to curb NET's production of controversial documentaries and replace it with a less controversial, government-friendly broadcaster, less hostile in particular to the Johnson, and later the Nixon administrations (NET ignored the demand and continued with the production of the critically acclaimed documentaries). At one point, President Nixon, frustrated with NET's documentaries criticizing his administration, especially its handling of the Vietnam War, almost managed to cut NET's $20 million funding grant in half. This led both the Ford Foundation and the CPB to threaten NET with funding withdrawal in early 1970, unless it merged its operations with WNDT. Not long after, the Ford Foundation brokered the merger of WNDT and NET, which took effect on June 29, 1970. Channel 13's call sign was changed to the present WNET on October 1, 1970. NET ceased network operations three days later, with PBS taking over the following day. The station continued to produce some shows for the national PBS schedule with the NET branding until early 1972, when they began to be identified as "WNET/13" programs; a formal consolidation of the corporation's separate national and local production facilities occurred later that year.

Following the merger, David Loxton established the TV Lab in 1972 with support from the Rockefeller Foundation and New York State Council on the Arts. TV Lab provided artists with equipment to produce video pieces through an artist-in-residence program. The Independent Documentary Fund and Video Tape Review series were both produces of TV Lab. TV Lab ended in 1984 when the CPB withdrew funds.

Since 1979, the station has been known on-air as "Thirteen". It continued to include Newark in its legal IDs (though logos for national productions read "New York") until the late 1990s. Since then, it has identified mostly as "New York", though it is still legally licensed to Newark.

Even after becoming a noncommercial station, channel 13 retained its original studios and offices at the Mosque Theater in Newark. The station eventually moved to the Gateway Center office building, also in Newark. In 1982, more than 20 years after becoming the New York area's flagship public television station, WNET moved its operations to the Hudson Hotel at 237 West 58th Street in Manhattan, while retaining the Gateway Center studios for a few more years.
