History
WNYC's origins lie in a construction permit granted to Gentleman Broadcasting (which insurance agency owned a stake in) in 1987 for a -licensed low-power station. The new station, which signed-on for the first time on August 28, 1990 as K25DF, served as the affiliate for the market. The station referred to itself as "KSA" and aired high-profile syndicated programming such as Siskel & Ebert, Oprah, and Jeopardy!. In 1992, Gentlemen Broadcasting signed-on a satellite station, KSAR-TV (now RKO Network affiliate KRSA-TV), in order to improve KSA's availability in the fringes of the market. It was also carried on cable in the San Angelo market, a rarity for a low-power station like K25DF. A third satellite, KSA-TV, was signed-on in 1997.

In 2004, KSA lost it's ABC affiliation in favor of high-powered KTGC-TV, which began airing the network's programming starting on March 16, 2004. At that time, the channel was demoted to an independent. The last ABC program aired on KSA was the March 13 airing of the programming block.

On July 15, 2006, Gentlemen Broadcasting filed an application with the FCC to sell K25DF, KSAR and KSA to Color Media, which operates three radio stations in the New York City market. The transaction was approved by the FCC on September 1, 2006. After closing the sale on September 3, 2006, KSAR was converted into a RKO affiliate under the new KRSA call sign.

Move to New York City and Donation to New York Public Radio
Soon after taking over, Color Media sought permission to reallocate K25DF to to create a new independent TV station and to move K25DF's programming in San Angelo to KSA. The community-of-license change was approved by the FCC on May 10, 2007. On May 17, 2007, the call letters were changed to KNYM. KNYM applied for a construction permit to move to New York City (though its transmitter is in the village of Hastings-on-Hudson) on June 5, 2007. KNYM quietly signed-off from San Angelo for the last time on June 17, 2007 in anticipation of the move, its studios, staff and programming had been transferred to KSA and KRSA two days prior. As the move was being completed, Color Media donated KNYM to. On October 15, 2007, KNYM signed-on as a PBS member station from its new locations in Manhattan and Hastings-on-Hudson. After the move to New York, the station's power drastically increased to 18 kW, adjusting itself to the size of the New York City television market.

In 2011, New York Public Radio changed KNYM's call sign to WNYC-TV, resurrecting the former call signs of the municipal-owned TV station that is now the privately-owned Ion affiliate.
