Doug is an American animated sitcom created by Jim Jinkins and produced by Jumbo Pictures. It originally aired on Nickelodeon from August 11, 1991, to January 2, 1994, and on ABC from September 7, 1996, to June 26, 1999. The show focuses on the early adolescent life and zany hijinks of its title character, Douglas "Doug" Funnie, who experiences common predicaments while attending school in his new hometown of Bluffington. Doug narrates each story in his journal, and the show incorporates many imagination sequences. The series addresses numerous topics, including trying to fit in, platonic and romantic relationships, self-esteem, bullying, and rumors. Many episodes center on Doug's attempts to impress his classmate and crush, Patti Mayonnaise.

Jinkins developed Doug from drawings in his sketchbook that he created over the course of the 1980s. Doug, a mostly autobiographical creation, was largely inspired by Jinkins's childhood growing up in Virginia, with most characters in the series being based on real individuals. He first pitched Doug as a children's book to uninterested publishers before Nickelodeon purchased the show. Following this, the series underwent further development, in which Jinkins meticulously detailed every aspect of the show's setting. Jinkins was insistent that the series would have a purpose and instructed writers to annotate each script with a moral. The show's unusual soundtrack consists largely of scat singing and mouth noises.

The series premiered on the cable network Nickelodeon, as the first of the original three Nicktoons alongside two other original animated series, Rugrats (which premiered directly after Doug) and The Ren & Stimpy Show (which premiered directly after Rugrats). The original run consisted of 52 episodes over four seasons that were broadcast from 1991 to 1994, with Games Animation and Ellipse Programmé co-producing. Due to Nickelodeon opting against renewing the show for a fifth season, The Walt Disney Company would acquire Jumbo Pictures alongside the Doug intellectual property, subsequently green-lighting the show for three additional seasons of 65 episodes. Jinkins made several creative changes during this time. The show moved to ABC's Saturday morning lineup, co-produced by Walt Disney Television Animation. In 1998, the series also aired on television syndication. It became a top-rated show, inspiring various books, merchandise, a live musical stage show, and a theatrical feature, Doug's 1st Movie, released as the series' conclusion in 1999. The series has seen multiple home video releases during its run.

The series revolves around Douglas "Doug" Funnie, an 11 (later 12)-year-old boy who wants to be another face in the crowd, but by possessing a vivid imagination and a strong sense of right and wrong, he is more likely to stand out. He keeps a journal, which he treats as an autobiography, as he records numerous experiences over the series, which range from learning to dance to getting a bad haircut. Doug Funnie and his family (which consists of his parents Theda and Phil, sister Judy, and dog Porkchop) move from the town of Bloatsburg to Bluffington after his dad receives a job promotion. Bluffington is in the United States but not in any specific U.S. state. However, Bluffington is loosely based on the city of Richmond, Virginia, where creator Jim Jinkins was born and raised.

Beyond the title character, Doug features a large ensemble cast of characters. Many of the series' ancillary characters, among them Ms. Wingo and Mr. Spitz, are based on authority figures from Jinkins' childhood.

Doug was created by animator Jim Jinkins. He was born in Richmond, Virginia in 1953, and grew up fascinated by drawing. He went on to animation and filmmaking at Ohio State University, and upon graduation, got a job working at PBS in their children's programming unit. Jinkins first sketched the character of Doug while doodling without thought, not aiming to create a character based on himself. In the 1980s, he began working on an autobiographical character named Brian, which he later changed to Doug, as it was a very common name. He began to view the character as his "alter-ego", drawing him in various silly and occasionally cynical scenarios in his sketchbook.

In 1984, Jinkins's career took a turn for the worse, as well as his personal life: he had a rough breakup and suffered injuries in a biking accident. During this time, he gained a new outlook on life. Desiring to "create a place where there was no overdue rent and no delinquent phone bills," he began doodling and formed the basis for Bluffington, the central location in Doug. The character's early designs were solidified alongside friend David Campbell at a small Mexican restaurant in New York. He later credited the character's odd coloring choices from being in a "margarita stupor". Campbell suggested he make Doug into a children's book, titled Doug Got a New Pair of Shoes, which was rejected by all of the city's publishing houses. Simon & Schuster was interested, but management changed before it purchased the pitch. The character made its first animated appearance in a 1988 Florida Grapefruit Growers commercial, and it was also used for a 1989 promotional bumper for the USA Network.

Meanwhile, cable network Nickelodeon, aiming to expand its content and find creative auteurs, began a search for animators to develop their first original animated series. This was very unusual for the time period, which often consisted of pre-licensed characters, such as Teenage Mutant Ninja Turtles and Where's Waldo?. Jinkins had actually worked at the network before it was renamed Nickelodeon; he was employed in the late 1970s, on their first show Pinwheel. Jinkins set up a meeting with executive Vanessa Coffey to show her the book prototype. Coffey ran out of the room ("which is, you know, disturbing," Jinkins would recall), but only to inform her boss that "This [Jinkins] guy is the real deal, and we're taking him to pilot." Employing voice artists and writers from New York, Jinkins created a pilot for Doug, titled Doug Can't Dance. It was one of three six-minute pilots chosen out of eight to premiere as Nickelodeon's debut animated series, or Nicktoons. It also tested the highest out of eight that were shown to test audiences, scoring the highest of eight points. The long contract development took nearly a year to complete. Jinkins made sure that his contract allowed him to take the series to another network if Nickelodeon did not complete the show's order.
