By any metric, The Simpsons is a uniquely successful show. Since making its debut in 1989, The Simpsons has become the longest-running American scripted primetime television series, which is quite impressive for an animated show many wrote off as children’s nonsense in its early days. Even though The Simpsons has experienced a noticeable drop-off in overall quality over the years, it still ranks as one of the greatest TV series ever made and its legacy is ensured no matter how long it limps on for.

More recently, The Simpsons has been mired in controversy for how its creators have handled criticisms of the character Apu. but that’s not what we’re here to discuss today.
