Millar Gough Ink

Background
Millar Gough Ink is a production company founded in 1997 by Miles Millar and Alfred Gough.

1st Logo (October 12, 1999-November 10, 2011)
Logo: In an office setting, at the forefront, we see a bottle filled with orange red ink in it labeled with the company name in an Impact font colored in, with only the bottom half in white. After one of the music variants are heard, a hammer (which if you look very closely, can be seen in the reflection of 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 4:3 prints of all episodes of Smallville.

FX/SFX: Entirely live-action.

Music/Sounds: Here are the music variants in this logo:
 * 1999: The closing theme of the show, along with a splattering sound.
 * 2001-2002: Just a sound of the bottle breaking.
 * Early 2002: An odd 3-note piano tune with an eerie sound effect.
 * 2002-2011: A reverberating 14-note synth-organ ditty.

Music/Sounds Variants:
 * On the Smallville season 1 episodes "X-Ray" and "Hug", the bottle breaking sound is absent.
 * On early season 2 episodes of Smallville, the reverberating cartoon ditty is somewhat slightly quieter before the bottle breaking sound appears.
 * Original airings use a generic theme and voiceover.

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. It also made an appearance on the 2006 television pilot of Aquaman, which was initially released on iTunes 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 words "MILLAR GOUGH". To the right of it is a beaker with a black water drop in it, and inside the drop, we see the text "INK".

FX/SFX: None.

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

Availability: Seen on Into the Badlands and The Shannara Chronicles. It's expected to appear on the upcoming Netflix show Wednesday.
