Karen says, "Nighttime around here is not exactly like nighttime at the Waltons." Like Knots Landing (1979), The Waltons (1972) was produced by Lorimar-Telepictures and aired on Thursdays on CBS. The two series were both part of CBS' Thursday night schedule from 1979 to 1981 with The Waltons (1972) airing at 8 o'clock and Knots Landing (1979) airing at 10 o'clock.
