In 1956, the WNHC stations were purchased by Philadelphia-based Triangle Publications."Triangle makes 4th purchase in year, buys WNHC-AM-FM-TV for $5.4 million." Broadcasting – Telecasting, May 28, 1956, pg. 82. Also that same year, WNHC-TV lost its CBS affiliation when that network purchased WGTH-TV in Hartford (channel 18, later WHCT and now Univision affiliate WUVN). This left channel 8 as a sole ABC affiliate, although it shared ABC programming with WATR-TV (channel 20, now WCCT-TV) in nearby Waterbury until 1966. Under Triangle ownership the WNHC stations moved to a new studio facility, on College Street in downtown New Haven, around 1960.
