WWTI is the ABC- affiliated television station for Upstate New York's North Country. Licensed to Watertown, it broadcasts a high definition digital signal on UHF channel 21 (or virtual channel 50.1 via PSIP) from a transmitter on Hayes Road in Copenhagen (a village of Denmark). The station can also be seen on Time Warner Cable channel 5 and in high definition on digital channel 889. Owned by the Nexstar Broadcasting Group, it has studios at Stateway Plaza (with an Arsenal Street/ NY 3 postal address) in Watertown. Syndicated programming on WWTI includes The Big Bang Theory, Dr. Phil, Judge Judy, and The Doctors among others.
Although technically operating as a separate station in its own right, WWTI is actually considered a semi-satellite of WSYR-TV in Syracuse. As such, this station clears all ABC programming and most local newscasts (see below) as provided by its parent but airs separate commercials and legal identifications. It simulcasts Who Wants to Be a Millionaire from WSYR weekday afternoons at 12:30 and airs The Dr. Oz Show weekday mornings at 9 (as opposed to the later airing at 4 on its parent outlet). Master control and some internal operations of WWTI are based at centralcasting facilities within WSYR's studios on Bridge Street in East Syracuse (a village of DeWitt).
