Fuzzy Door Productions

Background
Fuzzy Door Productions is an American film and television production company founded by Seth MacFarlane in 1998, with Erica Huggins as president of the studio. The company is best known for working on Family Guy, American Dad! and The Cleveland Show. In January 2020, the company signed a deal with Universal Television (the company had previously worked with their film division on the Ted films) and moved from its longtime home at the 20th Century Fox Studios lot to the Universal City Studios. The company did not use a logo until 1999, when Family Guy premiered.

1st Logo (January 31, 1999-April 27, 2020)
Logo: On a black background, we see a door partly open with a leopard print design on it. Below the door is the company name with a trademark symbol, both in the Lithos Pro Bold font.

Trivia: The name of the company and logo design comes from the leopard-printed fake fur-covered door to the house MacFarlane lived in when he was attending Rhode Island School of Design as an undergraduate in animation. This logo was designed by Cory Brookes, a friend and housemate of Seth's at the Fuzzy Door residence.

Variants:
 * Both 4:3 and 16:9 versions of the logo exist.
 * Sometimes, the logo fades in and out.

Technique: None.

Music/Sounds: Usually silent, though the first two episodes of Family Guy have a brief ditty that resembles the theme song.

Music/Sounds Variants:
 * On the DVD commentary for the first episode of Family Guy, the theme is heard over the dialogue, possibly because Fox used split-screen credits at the time and they wanted to give the logo closing music instead of it being silent.
 * On the DVD commentary for the fictional Family Guy episode "New Phone, Who Dis?" (aka "You Can't Handle the Booth!", a meta episode where the Griffins record DVD commentary for the aforementioned fictional episode), Peter talks over the logo, interrupting animation producer Sharon Smith and then he says "Um, Fuzzy Door! Bye!".
 * Some episodes of the aforementioned show have the last note of the show's theme song echo.
 * Otherwise, it's the end theme of the show, or a generic theme on Fox.

Availability: Common.
 * Seen on most episodes of Family Guy (with the last episode to use this logo being "Absolutely Babulous"), as well as The Cleveland Show, American Dad!, Bordertown, and the online series Seth MacFarlane's Cavalcade of Cartoon Comedy.
 * It was also seen on the live-action shows The Winner, Dads, Cosmos: A Spacetime Odyssey, Blunt Talk, and the first two seasons of The Orville, as well as at the end of the films Ted, A Million Ways to Die in the West, the DVD film Family Guy Presents: Stewie Griffin: The Untold Story, and Ted 2.
 * Some later episodes of Family Guy skip the logo, though some syndie prints add this logo to it. It is also often skipped on other shows, possibly due to time.
 * It was last used on the American Dad! episode "Cheek to Cheek: A Stripper's Story".

Legacy: This logo is a favorite amongst fans of Family Guy and Seth MacFarlane's works in general.

2nd Logo (November 10, 2019-)
Logo: On a navy blue background, the company name is seen in white and spaced out. In between the two words is a stylized white door that's cracked open.

Variant: On Cosmos: Possible Worlds, the logo's colors are inverted.

Technique: None.

Music/Sounds: None or the end theme of the show.

Availability: Current.
 * Debuted on the Family Guy episode "Peter & Lois' Wedding", and used in term with the previous logo until the end of April 2020. Also appears on Cosmos: Possible Worlds, The At-Home Variety Show, and newer episodes of American Dad! starting with "100 Years a Solid Fool".
 * It was recently seen on The End is Nye.
 * Currently used in tandem with the next logo.

3rd Logo (September 27, 2020-)
Logo: Same as the previous logo, but on a dark blue gradient background instead. A blue version of the door opens and it turns white, as the words fade in against the background.

Variant: Sometimes, the logo is shortened.

Technique: 2D animation.

Music/Sounds: A 3-note trumpet fanfare with a choir singing the company name. Presumably composed by Walter Murphy. Otherwise, none. Original Fox airings use a generic theme and a voiceover.

Availability: Current.
 * It debuted on the Family Guy episode "Stewie's First Word". Some Season 20 episodes of the show don't use this logo, most likely due to time constraints.
 * The music variant debuted on Season 3 of The Orville, subtitled New Horizons.
 * Currently used in tandem with the previous logo.

Legacy: This logo is considered boring compared to its predecessor, as well as another downgrade in a decade trend of simplified logos. The variants with animation and music are better received though.
