The Brady Bunch Hour (1977), Mrs. Columbo (1979), Joanie Loves Chachi (1982-1983), Dirty Sally (1974), and Richie Brockelman, Private Eye (1978). But a few--such as Lou Grant (1977-1982), Rhoda (1974-1978), Frasier (1993–2004), and Star Trek: The Next Generation (1987-1994)--were good ideas from the first, and proved the durability of their source material.
