The 1960s was a transformative decade for television, marked by the rise of color broadcasts and the expansion of programming options. Shows like The Andy Griffith Show and Star Trek became cultural phenomena, reflecting the social changes of the era. The introduction of the Nielsen ratings system also helped networks understand viewer preferences, leading to more targeted programming. This decade also saw the emergence of influential news programs, such as CBS Evening News with Walter Cronkite, which played a crucial role in shaping public opinion. The Vietnam War and the Civil Rights Movement were often covered, making television a vital source of information and a platform for social change.
