Beginning in the mid-1970s, miniseries based on novels captivated television audiences like never before. Networks poured money into the productions and reached huge numbers of viewers around the world. The key to these miniseries’ success are beloved characters that survive twists and turns that unfold over decades, including struggles to be accepted, whether in a loving relationship or within society. “Roots,” based on Alex Haley’s novel, was shown over eight consecutive nights in 1977 and attracted more viewers than any other television drama before. “Roots” was a cultural landmark that had a profound effect, shifting opinions and revealing the truth about the African-American experience of slavery. In “Rich Man, Poor Man” (1976), two starkly different brothers seek acceptance from their rough-edged immigrant father as they also build their lives in America, from post-World War II through the 1960s.
