Little Stranger, Inc.

Background
Little Stranger, Inc. is the production company of actress and creator Tina Fey, founded on January 5, 2001. The company is named after a loose translation of Fey's mother Greek maiden name Xenakes. According to Fey, it is also a nod to the "little stranger" who had come in and changed their lives.

1st Logo (October 11, 2006-January 31, 2013)
Visuals: On a black background, there is a tilted rectangle (it isn't tilted sometimes) with a white border with a photo inside it, and the white text "Comic Sans MS" on the top center. The photo tilts slightly. Here are all the variants used, each has the photo of the following:
 * A baby boy makes a funny face. The rectangle is stretched and tilted in the opposite direction, with the photo smaller and the text in a different font in this variant. Used in the pilot.
 * A girl in a peacock costume on a teal background (possibly resembles the NBC logo). (This is the most common of the variants.)
 * An alternate version exists on at least one episode, where the girl is pushed to the left to make room for another girl, both in the same peacock costume.
 * An edited-in video of a happy young girl on the same teal background replacing the girl. Used on at least one episode.
 * Two men (possibly John Cusack at the middle) and a woman (presumably Tina) looking at the camera during nighttime. The text is slightly positioned lower. Used on the episode centered in the "All Grown Up" idea.

Trivia: The girl in the peacock costume in one of the photos and its variant is Tina Fey's older daughter, Alice Zenobia Richmond, as a child. She wore the peacock costume for Halloween at the time, which the costume itself is an unintentional, yet indirect nod to NBC, the producer for a majority of the company's shows.

Technique: 2D computer animation with live-action photograph.

Audio: None or the closing theme.

Availability: Seen on 30 Rock.

2nd Logo (March 6, 2015-)
Visuals: On a white background, there is a 2D colored silhouette of the girl in the peacock costume from the previous logo, positioned over the crudely-drawn words "LiTtLE STRANGER," and "inc." The girl dances around, then takes a bow and returns to her normal position.

Variants:
 * Sometimes, it shares the screen with other logos.
 * A still version exists.

Technique: 2D computer animation.

Audio: A girl saying "Goodnight, everybody!" and another girl saying "Goodnight!" over some piano notes. Otherwise, the end theme that sometimes overlaps either all of the audio or of the entire dialogue. On Great News, none.

Audio Variants:


 * On the first season of Unbreakable Kimmy Schmidt, the girl saying "Goodnight!" is removed.
 * On an earlier episode of Girls5Eva, the first few piano notes are removed.

Availability: Seen on Unbreakable Kimmy Schmidt, Great News, Girls5Eva, Mr. Mayor and Mulligan.
