I can think of a few more shows that started as midseason replacements:
The William Bendix version of "Life of Riley" in the winter of 1953;
"The Hollywood Palace" in January 1964;
"The Smothers Brothers Comedy Hour" in February 1967;
"Rowan and Martin's Laugh-In" in January 1968;
"Sanford and Son" and "Emergency!" in January 1972;
"Barnaby Jones" in January 1973;
"Good Times" in January 1974;
"Barney Miller," "The Jeffersons," "Baretta," and "S.W.A.T." in January 1975;
"Laverne and Shirley," "The Bionic Woman," and "Donny and Marie" in January 1976 ("One Day at a Time" debuted in December 1975);
"The White Shadow" and "Diff'rent Strokes" in November 1978;
"Real People" in the spring of 1979 (not sure of the premiere date);
"Knots Landing" in (I believe) November 1979;
"That's Incredible!" in January 1980;
"Dynasty" in January 1981.
And I can think of four monster hits that started as summer shows: "The Lawrence Welk Show" and "The $64,000 Question" in 1955;
"Hee Haw" and "The Johnny Cash Show" in 1969.
