This makes WPMT the second-oldest continuously broadcasting UHF station in the country, only behind WSBT-TV in South Bend, Indiana (although WSBT moved from its original channel 34 to channel 22 in the late 1950s, making WPMT the oldest UHF station that broadcasts continuously on the same virtual channel number to this day).
In 1961, the station became a CBS affiliate and joined WHP-TV (channel 21) in Harrisburg and WLYH-TV (channel 15) in Lebanon to form the Keystone Network.
A year earlier, WPMT had added programming from The WB, half-owned by Tribune, in off-hours.
However, cable customers could watch the full WB schedule on WPHL-TV in Philadelphia.
In April 1983, Susquehanna sold WSBA-TV to Idaho-based Mohawk Broadcasting, who changed its call letters to the current WPMT.
