His stage success brought him to the attention of producer Leland Hayward, and in 1964 he began a regular stint as a cast member on Hayward's satirical NBC-TV series "That Was the Week That Was". Starting in the late 1960s, Browne increasingly became a guest star on TV on both comedy and dramatic shows like "Mannix", "All in the Family", "Good Times", "Sanford and Son", "The Cosby Show", "A Different World" and dozens of other shows. He also was a regular on "Soap" where he played Saunders, the erudite butler from 1979–81. Browne later guest-starred on "Benson" with Robert Guillaume, who had himself previously been in the cast of "Soap". Browne's appearances on "The Cosby Show" won him an Emmy Award in 1986 for his guest role as Professor Foster.
