The Simpsons shorts in the context of "Simpson family"

Homer Jay Simpson is the main protagonist of the American animated sitcom The Simpsons. Part of the titular family, Homer made his television debut in the short "Good Night" on The Tracey Ullman Show on April 19, 1987. Cartoonist Matt Groening crafted and designed Homer while waiting in the lobby of James L. Brooks's office. Initially called to pitch a series of shorts based on his comic strip Life in Hell, Groening instead developed a new set of characters. After two years on The Tracey Ullman Show, the Simpson family received their own series, which premiered on Fox on December 17, 1989.

Homer is the patriarch of the family; he is married to Marge, with whom he has three children, Bart, Lisa, and Maggie. As the family's primary provider, Homer primarily works as a safety inspector at the Springfield Nuclear Power Plant. He represents numerous American working-class stereotypes: he is overweight, balding, immature, unintelligent, outspoken, aggressive, lazy, ignorant, unprofessional, and deeply fond of beer, junk food, and television. Despite these flaws, Homer is fundamentally a kind-hearted man and fiercely protective of his family, particularly during crucial moments.

The Simpsons is an American animated sitcom created by Matt Groening and developed by Groening, James L. Brooks and Sam Simon for the Fox Broadcasting Company. It is a satirical depiction of American life, epitomized by the Simpson family, which consists of Homer, Marge, Bart, Lisa, and Maggie. Set in the fictional town of Springfield, in an unspecified location in the United States, it caricatures society, Western culture, television and the human condition.

The family was conceived by Groening shortly before a solicitation for a series of animated shorts with producer Brooks. He created a dysfunctional family and named the characters after his own family members, substituting Bart for his own name; he thought Simpson was a funny name in that it sounded similar to "simpleton". The shorts became a part of The Tracey Ullman Show on April 19, 1987. After three seasons, the sketch was developed into a half-hour primetime show and became Fox's first series to land in the Top 30 ratings in a season (1989–1990).

Bartholomew Jo-Jo "Bart" Simpson is one of the main characters in the American animated television series The Simpsons who is part of the titular family. Widely regarded as one of the greatest fictional characters of all time, he was named by Time as one of the most important people of the 20th century.

Bart made his television debut in the short "Good Night" on The Tracey Ullman Show on April 19, 1987. Cartoonist Matt Groening created and designed Bart while waiting in the lobby of James L. Brooks's office. Initially called to pitch a series of shorts based on his comic strip Life in Hell, Groening developed a new set of characters. Unlike the other Simpson family members, who were named after Groening's relatives, Bart's name is an anagram of brat. After two years on The Tracey Ullman Show, the Simpson family received their own series, which premiered on Fox on December 17, 1989. Bart has appeared in every episode of The Simpsons except "Four Great Women and a Manicure".

Lisa Marie Simpson is one of the main characters in the animated television sitcom series The Simpsons. She is the middle child of the Simpson family. Voiced by Yeardley Smith, Lisa was born as a character in The Tracey Ullman Show short "Good Night" on April 19, 1987. Cartoonist Matt Groening created and designed her while waiting to meet James L. Brooks. Groening had been invited to pitch a series of shorts based on his comic Life in Hell, but instead decided to create a new set of characters. He named the older Simpson daughter after his younger sister Lisa Groening Bartlett. After appearing on The Tracey Ullman Show for three years, the Simpson family were moved to their own series on Fox, which debuted on December 17, 1989. Lisa has appeared in every episode of The Simpsons except for "Carl Carlson Rides Again".

Intelligent, kind, and passionate about the planet and all living things, Lisa Simpson is the second child of Homer and Marge. She is the younger sister of Bart, and the older sister of Maggie. At age 8, Lisa's high intellect and left-wing political stance creates a barrier between her and other children her age. She is a loner and a social outcast. Lisa is a vegan, a bibliophile, a strong environmentalist, a feminist, and a Buddhist. Lisa's character develops many times over the course of the show: she becomes a vegetarian in season 7, converts to Buddhism in season 13, and becomes a vegan in season 32. A strong liberal and activist for peace, equality, and the environment, Lisa advocates for a variety of political causes (e.g. standing against apartheid in South Africa and supporting the Tibetan independence movement) which sets her against most of the people in Springfield. However, she can also be somewhat intolerant of opinions that differ from her own, often refusing to consider alternative perspectives and showing a feeling of self-righteousness. In her free time, Lisa enjoys many hobbies such as reading and playing the baritone saxophone. She has appeared in other media relating to The Simpsons—including video games, The Simpsons Movie, The Simpsons Ride, commercials and comic books—and inspired a line of merchandise.

Abraham Jay "Abe" Simpson II, better known as Grampa Simpson, is a recurring character in the animated television series The Simpsons. He made his first appearance in the episode entitled "Grandpa and the Kids", a one-minute Simpsons short on The Tracey Ullman Show, before the debut of the television show in 1989.

Grampa Simpson is voiced by Dan Castellaneta, who also voices his son, Homer Simpson. He is the paternal grandfather of Bart, Lisa and Maggie Simpson. In the 1,000th issue of Entertainment Weekly, Grampa was selected as the "Grandpa for The Perfect TV Family". Grampa is a World War II veteran and retired farmer who was later sent to the Springfield Retirement Castle by Homer. He is known for his long, rambling, often incoherent and irrelevant stories and senility.
