WFTY-DT, virtual channel 67 (UHF digital channel 23), is a UniMás owned-and-operated television station serving Long Island, New York, United States that is licensed to Smithtown. The station is owned by Univision Communications, as part of a duopoly with WXTV-DT (channel 41). It operates as a satellite station of Newark, New Jersey-based WFUT-DT (channel 68). The stations share studios and offices in Teaneck, New Jersey, and its transmitter is based at its facility in Middle Island.
The station first signed on the air on November 18, 1973 as WSNL-TV, originally licensed to Patchogue. The station was founded on the premise of there being over three million people living on Long Island who were underserved by local television news coverage; with all the network affiliates based in Manhattan, it was rare to see more than one or two news stories a day focusing on Long Island.
WSNL went on the air with two daily newscasts: a half-hour early evening broadcast and an hour-long newscast at 10 p.m., in addition to coverage of high school sports; it also carried some off-network reruns and first-run syndicated programming. One of the more noteworthy series among this batch was Phil Donahue, which had been in national syndication since 1970, but had not been available in the crucial New York City market since WPIX (channel 11) dropped the show in the fall of 1970. And after the station's demise, would not find another outlet until WOR-TV (channel 9) acquired the local rights to the program in 1976, followed by WNBC Channel 4 in 1977. The station also carried games from the short-lived New York Stars of the World Football League in 1974.
