WNJU (channel 47) is a television station licensed to Linden, New Jersey, United States, serving as the Telemundo outlet for the New York City area.

Through a channel sharing agreement with WNBC, the two stations transmit using WNJU's spectrum from an antenna atop One World Trade Center.

Conceived to replace WNTA-TV as northern New Jersey's commercial station and to provide specialty ethnic programming in the tri-state area, WNJU began broadcasting on May 16, 1965.

WNJU's program lineup, which catered to the tastes of the Puerto Ricans and Dominicans in the tri-state area, often outperformed the Spanish International Network and its mostly Mexican shows in the local ratings.

The studio sold the station in 1979 to a consortium headlined by Norman Lear and Jerry Perenchio, but plans to convert to subscription television operation were scrapped.

[3][a] Edwin Cooperstein, the president of the permittee and director of radio and television at Fairleigh Dickinson University and who had been the head of WNTA-TV (channel 13) when it was a commercial outlet, had proposed the station a year earlier, to transmit from a tower in the New Jersey Meadowlands.

[6] Even before filing for the permit, New Jersey Television Broadcasting had set up in the Mosque Theater (now Newark Symphony Hall) at 1020 Broad Street in Newark, WNTA-TV's former home, which included a 10,000-square-foot (930 m2) studio that was the largest at any non-network TV station in the United States;[7] it announced it would use the former WNTA-TV transmitter site in West Orange and stocked its staff with several channel 13 veterans.

[9] However, within a month of obtaining the permit, the new WNJU-TV decided on an Empire State Building site for its transmitter, which was approved by the FCC in April 1964.

[15] In 1967, WNJU-TV went all-color and also became the first New York-area television station to automate its transmitter;[16] it opted not to move to the World Trade Center when it was built for financial reasons.

[19] WNJU-TV was sold in the fall of 1970 for $8 million (a fairly high price for a UHF station in that time) to Screen Gems Broadcasting, a subsidiary of Columbia Pictures.

[21] In 1975, WNJU-TV received a short-term license renewal for only one year (instead of the then-customary three) for failure to abide by a previous pledge to limit commercials to 16 minutes per hour, which the station exceeded more than 16 percent of the time.

[24] By focusing on the large Puerto Rican community in New York, WNJU was able to beat the Spanish International Network's WXTV (channel 41), with its comparatively more Mexican programming, in the ratings.

[27][28] Jerry Perenchio, one of the shareholders in Chartwell, and his Tandem Productions acquired 80 percent of WNJU-TV from Columbia Pictures in late 1979 for $5 million.

NetSpan's founding affiliates were WNJU, ethnic independent KSCI-TV channel 18 for the Los Angeles market, and Chicago's WBBS-TV.

There was no space for a digital facility at the Empire State Building, so a permanent site in West Orange was used along with a secondary transmitter at 4 Times Square to improve signal levels in Queens and on Long Island.

[54][55] On January 14, 2022, WNJU announced that it would move its studios into NBC's headquarters at 30 Rockefeller Plaza in late 2023, sharing the second floor space with WNBC; New York City was the last NBC–Telemundo duopoly market where the two networks' stations maintained separate facilities.
