The golden age of American animation was a period in the history of U.S. animation that began with the popularization of sound synchronized cartoons in 1928 and gradually ended in the 1960s when theatrical animated shorts started to lose popularity to the newer medium of television. Animated media from after the golden age, especially on television, were produced on cheaper budgets and with more limited techniques between the 1960s and 1980s.

Animation in the United States in the television era was a period in the history of American animation that slowly set in with the decline of theatrical animated shorts and the popularization of television animation that started in the late 1950s, reached its peak during the 1970s, and ended around the mid-1980s. This era is characterized by low budgets, limited animation, an emphasis on television over the theater, and the general perception of cartoons being primarily for children. Due to the perceived cheap production values, poor animation, and mixed critical and commercial reception, the era is generally looked back upon negatively by critics and animation historians. The television animation of this period is often referred to as the dark age of American animation, while the theatrical animation from the time is sometimes referred as the bronze age.
