Discovery Networks

Background
Discovery Networks, (more commonly known as Discovery Channel) is a popular cable channel that first launched in 1985 as The Discovery Channel. The channel shows programming about history, science, and technology. It is most well known for its annual "Shark Week", a week-long programming block about sharks that first aired in 1988. Since 2010, it has been the longest-running cable programming event in history.

1st Logo (2002-2009)
Logo: On a black background, white lines flicker across the screen, revealing parts of the word "Impact". A white flash comes through from left to right and creates a radial flash (with blue lines surrounding it) underneath "Impact". Then from the radial flash, it reveals to be a spinning globe on a blue line with "NETWORKS" in it and the background changes to an animated background in a blue gradient. The globe spins as the background slowly animates.

Variants:
 * A more common short version exists where it starts as usual, but the background animates faster.
 * On some shows, a copyright stamp appears below.
 * Sometimes, "in association with" appears on top of the logo.
 * Another version has "produced in association with" appear on top of the logo with "CHANNEL" replacing "NETWORKS".

FX/SFX: The flash, the moving background and the lines.

Music/Sounds: A swoosh with a 2-note choir. Other original shows had the closing theme over it.

Availability: It was very common on Discovery channels in the 2000s, but is rare now. It appeared on most original Discovery productions from the time such as Dirty Jobs and How It's Made. In Latin America, this was also known to plaster other logos from syndicated programs. This could be seen on on Discovery channels such as Discovery Kids and Discovery Home and Health. Since this design's retirement in 2009, however, original logos from syndicated productions are now present.

Editor's Note: An amazing logo with proper timing and appropriate sound effects.

2nd Logo (2009-)
Logo: On a black background, a small, spinning globe zooms in to the left of the screen. A letter "D" comes out of the globe while the letters "iscovery" appear to finish the word and the word "NETWORKS" appears below.

FX/SFX: The spinning globe and words.

Music/Sounds: A deep synth pad.

Availability: Current. Seen on most Discovery programs from the era.

Editor's Note: Because of the simplistic animation, the logo looks like it was done by a beginner, but in summary, the animation is improving.
