Xbox

1st Logo (April 2001)
Visuals: On a black background, there is a large, pointy X facing towards the screen, Below it is "XBOX", also in , which then shines and two lines make it black and turns green again. After the animation ends, "XBOX" cuts out and the green X fades out.

Technique: Simple CGI.

Audio: None.

Availability: Only seen on early prototype Xbox dashboards. This startup is known as "ani.bin", with no leftovers of it in the Xbox code. The next startup is known as "ani2.bin" in the code.

2nd Logo (November 15, 2001-August 2005)
Visuals: There is a blob forming in a  and black laboratory. It keeps moving and moving, but everything zooms out in light and the same  X as before is seen. Below it is "XBOX" in the same color and font as the previous logo, and in a few seconds, the 1987-2012 Microsoft logo appears on the bottom.

Variants:
 * Apparently, in late development, the logo was originally going to respond to button inputs of A, B, X, Y, Black, White, and the left stick. These inputs would control animation speed, fog, shadows, camera position, intensity of the blob, and shields. In the final build of the kernel, the library for handling controller input is not loaded on boot, so this code (and therefore the interactivity) is unused.
 * In later prototype Xbox dashboards, a section of shields spin around the blob, the animation is slightly slower and the 1987-2012 Microsoft logo appears late and is in.
 * A still version with a white background is seen when you play an Xbox game on an Xbox 360.
 * When playing an Xbox game on an Xbox One or an Xbox Series X or S, the Microsoft logo is removed, presumably because they changed their logo since then. Also, the entire logo is in 60fps (original consoles have the logo at 30fps, only to switch to 60fps when the logo is being revealed).

Technique: CGI rendered in real-time. None for the still version.

Audio: Some deep synth bass notes with thunderclaps, followed by a high-pitched synthesized tune. It was composed by Brian Schmidt, who is known for composing music for pinball and video games.

Audio Variants: The still version is silent.

Availability: It appears as the start-up on all models of the original Xbox console, which can be found for cheap on many auction sites or thrift stores (such as Goodwill or The Salvation Army). Also appears when playing an Xbox game on an Xbox One or Xbox Series console. The "shields" variants only appears in later prototype Xbox dashboards.

Legacy: This is a very nostalgic logo among gamers.

3rd Logo (Error variant) (November 15, 2001-August 12, 2008)
Visuals: There is an exploding flash with  dots and they all form a  bubble circle. It zooms in when bacteria-like things appear, and then flash zooms in the Xbox logo without the "X". It shines exactly like the previous logo, and in a few seconds, it explodes. After that, it displays this in Arial: arial French, German, Spanish, Italian, and Japanese translations appear below.

Technique: CGI by REZN8.

Audio: An edited version of the ending of "Sunshower" by Secret Hate, with an explosion sound.

Availability: Can be seen if an original Xbox game is inserted into a DVD/Blu-ray player (or any PC or gaming system that plays DVDs or Blu-rays, like the PS2/PS3 for example).

4th Logo (Xbox LIVE variant) (August 16, 2002-May 11, 2010)
Visuals: It begins with a black background, and then an light shines brightly with several streaks. After this, a neon hexagonal grid appears as the camera zooms out. Eventually, it zooms out enough to reveal the "X" logo along with the "XBOX" text. The camera pans and rotates until the XBOX logo is seen from the top, and center. During the camera motion, the light is revealed to be coming from the letter "I" in "LIVE", and the letters "L", "V", and "E" slide in from the sides and light up. The "I" continues to shine from the top.

Variant: On the prototype of Crash vs. Spyro Racing, a different version was seen. The orange light and the streaks are seen moving from left to right as the camera rotates. The green grid pulsates in time with the sounds. Then, many orange triangular prisms come together and form the "XBOX LIVE" logo, while the camera zooms out. The "LIVE" text glows, and then the light on top of the "I" also glows brighter.

Technique: CGI by REZN8.

Audio: Various whooshes with a short synth theme. The variant uses the sounds from the 2nd logo with additional sound effects.

Availability: Can be seen if "Xbox LIVE" is selected on the dashboard version "4920". Also seen on various Xbox LIVE promos, and whenever an Xbox Live Arcade disc is launched.
