On September 28, 1981, WRGB swapped affiliations with WAST (which would become what is now WNYT on the day of the switch) and became a CBS affiliate. WAST had only picked up the CBS affiliation four years earlier, but had remained stubbornly in third place behind WRGB and WTEN. Under the circumstances, when its affiliation contract with WAST ran out, CBS jumped at the chance to align with long-dominant WRGB. The switch made WRGB the third station in the Capital District to affiliate with CBS, with the newly-rechristened WNYT taking over the NBC affiliation. The network had originally aired on WTRI, forerunner of WNYT, from 1954 to 1955, then moved to WCDA (now WTEN) from 1955 to 1977.
