Apple has used a variety of advertising campaigns to promote its iPod portable digital media player. The campaigns include television commercials, print ads, posters in public places, and wrap advertising campaigns. These advertising techniques are unified by a distinctive, consistent style that differs from Apple's other ads.

The more notable commercials and print advertising feature dark silhouetted characters against bright-colored backgrounds. The silhouettes are usually dancing, and in television commercials are backed by up-beat music. The silhouettes are also usually holding iPods and listening to them with Apple's supplied earphones. These appear in white, so that they stand out against the colored background and black silhouettes. Apple changes the style of these commercials often depending on the song's theme or genre. Apple is also changing the style of their iPod Touch and now making it more suitable for children.

The original television commercials and posters featured solid black silhouettes against a solid bright color, which usually changed every time the camera angle changed. Some of the television adverts also depict highlights on the silhouettes using darkened shades of the background color, and shadows on the floor. Since then, various commercials in the campaign have changed the format further:

He is voiced by cartoonist Seth MacFarlane and first appeared on television, along with the rest of the family in the 15-minute short on December 20, 1998. Peter was created and designed by MacFarlane himself. MacFarlane was asked to pitch a pilot to the Fox Broadcasting Company based on Larry and Steve, a short made by MacFarlane which featured a middle-aged character named Larry and an intellectual dog, Steve. After the pilot was given the green light, The Griffin family appeared on the episode "Death Has a Shadow".

Peter is married to Lois Pewterschmidt and is the father of Meg, Chris and Stewie; he also has a dog named Brian. He has worked at a toy factory and at Quahog's Brewery. Despite the suburban blue-collar routine of his life, he has had a number of remarkable experiences.

Peter's voice was inspired by a janitor that MacFarlane heard at his school. His appearance was a redesign of the protagonist Larry from MacFarlane's previous animated short films, The Life of Larry and Larry & Steve. The Peter Griffin character has received generally mixed to positive reviews from critics. He has appeared in several pieces of Family Guy merchandise, including toys, t-shirts and a video game, and has made crossover appearances in other shows, including The Simpsons, South Park, American Dad and the Family Guy spin-off The Cleveland Show.
