When did animated TV shows become mainstream?

Animated TV shows began to gain mainstream popularity in the mid-20th century, but several key milestones mark their evolution into a significant part of popular culture:

1. Early Beginnings (1920s-1930s): Animation started in the 1920s with short films, but it was not until the 1930s that characters like Mickey Mouse and Betty Boop became household names through theatrical shorts.
2. The First Animated TV Show (1949): The first animated series aimed at television was Crusader Rabbit, which premiered in 1949. While it was a modest success, it laid the groundwork for future animated programming.
3. The Golden Age of Animation (1950s-1960s): During this period, studios like Warner Bros. and Hanna-Barbera transitioned from theatrical shorts to television. Shows like The Flintstones (1960) became immensely popular, marking the first prime-time animated series and demonstrating that animated shows could attract adult audiences.
4. Saturday Morning Cartoons (1960s-1980s): The 1960s saw the rise of Saturday morning cartoon blocks aimed at children, featuring shows like Scooby-Doo, Where Are You! (1969) and Super Friends (1973). This era solidified animation’s role in children’s programming and created a significant market for animated content.
5. Cultural Impact in the 1990s: The 1990s marked a renaissance for animated TV shows, with the emergence of critically acclaimed series like The Simpsons (1989), which appealed to both adults and children. Other notable shows, such as Batman: The Animated Series (1992) and Animaniacs (1993), helped elevate the status of animation in mainstream media.
6. Diversity of Animation (2000s-Present): The 2000s and beyond saw an explosion of diverse animated programming, including shows like SpongeBob SquarePants (1999), Avatar: The Last Airbender (2005), and Adventure Time (2010). These series pushed the boundaries of storytelling and animation styles, appealing to a wide range of audiences.
7. Streaming Era: With the advent of streaming services in the 2010s, animated shows gained even more visibility. Platforms like Netflix, Hulu, and Disney+ have produced and promoted original animated content, further solidifying animation’s place in mainstream entertainment.
