[1] The station made its debut as WKOP on July 15, 1947, from studios on the fourth floor of 34 Chenango Street; it was affiliated with the Mutual Broadcasting System.

[1] WKOP launched WKOP-FM, which initially aired Rural Radio Network programming, in 1954;[5] it also expressed interest in television, but the FCC denied its bid to add VHF channel 7 to the market in 1952.

[9] Just days after his appointment, WKOP sustained damage when a fire was set in the Weeks and Dickinson music store in which it had been housed since its launch.

[10] The fire, it turned out, had a direct connection to the station: it had been started by a 21-year-old Johnson City man, Michael Fullman, who had briefly been a DJ as "Mike Eldredge" on WKOP in 1973.

[21] The 16 Wicks radio stations were sold to Citadel Communications for $77 million in late 1998, by which time WKOP was airing an adult standards format.

[23] The move was proposed as a swap of the two stations' frequencies, even though they aired the same programming;[24] it never came to pass, with WINR being sold to Clear Channel Communications instead.

[28] In 2012, Cumulus, which had acquired Citadel out of bankruptcy, transferred WYOS and its other Binghamton outlets to Townsquare Media as part of a 65-station swap.

In a statement to the media, Townsquare's Binghamton cluster manager noted that WYOS was not selling nor airing local advertising at the time.
