Discovery Networks

Background
Discovery Networks is the television division of Discovery, Inc. (formerly Discovery Communications and Cable Educational Network Inc.), which was an American multinational mass media factual television conglomerate based in New York City.

Discovery Communications was originally established in 1985 as a namesake and flagship brand called Discovery Channel, first launched on June 17, 1985 before its actual establishment in 1994 as Discovery Communications. On September 17, 2008, Discovery Holdings divested its interest in Ascent Media, and reorganized its remaining businesses around a new publicly traded holding company, Discovery Communications, Inc. On July 31, 2017, Discovery announced it would acquire Scripps Networks Interactive, owner of networks such as Food Network and HGTV, for $14.6 billion, pending regulatory approval. On March 6, 2018, the acquisition was completed, with the combined company renamed as Discovery, Inc. At this time, SNI shareholders own 20% of Discovery's stock. Discovery will retain an operational hub in SNI's home city of Knoxville, but planned to move its corporate headquarters from Silver Spring, Maryland, where it has operated since 2003, to New York City in late-2019.

Following the acquisition, Discovery began to integrate personalities from the two companies into each other's programming, and began to produce new programs (such as a revival of TLC's While You Were Out in conjunction with HGTV, and a competition series between the stars of Food Network's Ace of Cakes and TLC's Cake Boss) to serve as vehicles for crossovers between personalities from Discovery and SNI's networks.

In May 2021, AT&T announced that it had proposed to spin-off WarnerMedia and merge it with Discovery, Inc. to form a single company Warner Bros. Discovery, under Discovery Inc.'s CEO David Zaslav. In December 2021, it was announced that the deal was approved by the European Commission and the merger was completed by April 8, 2022 afterwards.

1st Logo (1995-2002)
Note: The 2nd video starts at 1:43.

Logo: On a black background, we see the words "Impact" in an Aurora font. Underneath is the word "Segoe UI" in a Futura font, and with a 3D earth spinning right next to it.

Variants:
 * The trademark symbol may be replaced with a registered symbol.
 * Sometimes, the logo is zoomed in.
 * Sometimes, "Segoe UI" is in a box.

FX/SFX: The globe rotating.

Music/Sounds: A synth choir note with a timpani beat.

Music/Sounds Variants:
 * Sometimes, it is silent instead.
 * On some shows, the closing theme is heard.

Availability: Was common on every Discovery channel program in the time period, but it is rare nowadays.

2nd Logo (2000-2009)
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.

Legacy: An amazing logo with proper timing and appropriate sound effects.

3rd Logo (2009-2018, 2019, 2009-present (SEA and Latin America))
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.

Variant: A short version exists at the end of some shows.

FX/SFX: The spinning globe and words.

Music/Sounds: A deep synth pad. The short variant has the theme being faster.

Availability: Common. Seen on most Discovery programs from the era. This makes a surprise appearance come-back on Discovery Southeast Asian prints of The Day I Ran China. Despite the logo being retired worldwide, it is still currently used in Latin America and Southeast Asia, as explained on The Day I Ran China.

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

4th Logo (2018- )
Logo: On a white background, we see the 3D earth. Then the "D" from before rotates beside it and faces to its usual position. Besides it are the words "iscovery" in the same font as before. The globe continues to rotate until it either fades out or cuts out.

Variant: On The Day I Ran China, a in-credit version of this logo was used; the logo's animation is superimposed on the show's last seconds. On Discovery Southeast Asian prints, the previous logo is used instead.

FX/SFX: The "D" and the earth rotating, and the camera revealing the company name. CGI animation that's at least better than the previous logo.

Music/Sounds: The show's ending theme.

Availability: Current, but it may not last. Seen on later episodes of The Rachael Ray Show replacing the Scripps Networks Interactive logo. It also appeared on The Day I Ran China as a variant. Due to WarnerMedia's merge with Discovery, Inc. to form Warner Bros. Discovery on April 8, 2022, this logo's days might be numbered.

Legacy: Despite the namesake Discovery Channel having changed their logo in 2019, this logo was still used as a Discovery Networks and Discovery, Inc. logo.
