Background
Millar Gough Ink is an American television production company that has co-produced the short-lived series The Strip, the Superman prequel television series Smallville, the 2006 television pilot of Aquaman, the 2011 Charlie's Angels revival, the AMC series Into The Badlands, the MTV series The Shannara Chronicles and the upcoming 2022 Netflix series Wednesday. It was founded in 1997 by Miles Millar and Alfred Gough, but they did not use the logo until October 1999.

1st Logo (October 12, 1999-November 10, 2011)
Logo: In an office, we see a bottle with orange red ink inside of it labeled the stacked words reading with the company name in an Impact font colored in a -white gradient. After one of the music variants are played, a hammer (which, if you look very, very closely, you can see a hammer falling down, as seen in the reflection on the bottle) falls down on top and breaks the bottle, causing the ink in it to spread everywhere, covering up the whole screen.

Variant: There exists an open-matte version of the logo. This can be seen on 2003 DVD releases, Channel 4 and E4 airings of season 1 or 4:3 prints of all episodes of Smallville and the short-lived series The Strip.

FX/SFX: The hammer falling, the hammer smashing the ink bottle, the ink spreading, the ink covering the screen. It's all entirely live-action. The live-action logo was made by Alfred Gough and Miles Millar.

Music/Sounds: There are music variants: Both music variants ended with the sound of a glass breaking or the ink spreading, sometimes, louder.
 * October 1999: The closing theme of the show before the ink spreading sound.
 * October 2001-February 2002: Just a sound of the glass breaking.
 * Early 2002: An 3-note odd, piano tune, accompanied by an eerie sound effect.
 * September 2002-November 2011: An 13-note, reverved, cathedral organ ditty, accompanied by an 7-note instrumental tune.

Music/Sounds Variants:
 * On the episodes "X-Ray" and "Hug" of the 1st season of Smallville, the glass shattering sound is absent.
 * On the early episodes of the 2nd season of Smallville, the 2002-2011 music variant is somewhat a little quieter before the glass breaking sound is heard.
 * Most of the original airings (e.g The CW) use a generic theme and a voice over.

Availability: Common. First seen on the short-lived series The Strip, and later seen on Smallville and the 2011 remake of Charlie's Angels on ABC, Sony Crackle and the CTV Throwback in Canada. It also made an appearance on the 2006 television pilot of Aquaman, which was initially released on iTunes on July 2006 and later included as a bonus feature on the Blu-ray release of Justice League: Crisis on Two Earths.

2nd Logo (November 15, 2015-)
Logo: On a black background, we see the stacked dark red words "MILLAR GOUGH". To the right of it is a dark red beaker with a black water drop in it, and inside the drop, we see the dark red text "INK".

FX/SFX: None.

Music/Sounds: None, or the ending theme of the show.

Availability: Currently seen on the 2015 AMC series Into the Badlands and the 2016 MTV series The Shannara Chronicles. It's expected to appear on the upcoming 2022 Netflix series Wednesday.

Legacy: None.
