and NBC affiliate WWLP in Springfield, Massachusetts. In addition, WFFF and WVNY also became sisters with fellow Fox and ABC affiliates WXXA-TV and WTEN, respectively, in Albany, New York. These stations also serve Bennington County, Vermont, making Nexstar responsible for Fox and ABC programming in 13 of the 14 counties in Vermont. The lone exception, Windham County, is served by Boston's WFXT and WCVB-TV, respectively (ABC programming in Windham County is also available through Manchester, New Hampshire's WMUR-TV). On June 15, 2016, Nexstar announced that it has entered into an affiliation agreement with Katz Broadcasting for the Escape, Laff, Grit, and Bounce TV networks (the last one of which is owned by Bounce Media LLC, whose COO Jonathan Katz is president/CEO of Katz Broadcasting), bringing one or more of the four networks to 81 stations owned and/or operated by Nexstar, including WFFF-TV and WVNY. Simultaneous substitution problems WFFF-TV has significant viewership in the much larger Montreal market because it is available over-the-air alongside other Vermont stations and used as the Fox station on Vidéotron's cable systems. As the youngest full-power station covering the entire market, it still relies heavily on Montreal for advertising revenue while the area's other stations have somewhat lessened their dependence on advertising. In 2003 and 2004, WFFF-TV was involved in a "commercial war" with Montreal's CJNT-TV. For some time, its commercials on non-network programs such as That '70s Show were blocked by simultaneous substitution (simsub) on Montreal cable systems. Under Canadian Radio-television and Telecommunications Commission (CRTC) regulations, simultaneous substitution demanded the cable companies in Canada replace WFFF-TV's signal with CJNT-TV's signal when the same program and episode was running at the same time. This is the same practice as the FCC's syndication exclusivity rule in the United States. In response, WFFF-TV frequently shifted its schedule to keep its commercials from being blocked in Montreal. In response to this station's schedule shuffling, CJNT moved its schedule accordingly to retain simsub rights. This resulted in a cat-and-mouse game of changing programming schedules every few weeks leaving viewers confused. The changes usually occurred with little to no advance warning, sometimes making local schedules in TV Guide (both U.S. and Canadian versions) outdated by the time they were published. WFFF-TV eventually solved the problem by adding a second daily airing of That '70s Show, giving it access to a second strip of programming from the distributor which was available only
