GMM Tai Hub

Background
GMM Tai Hub Co.,Ltd. or GTH (จีทีเอช) was a film and television company in Thailand from 2004 to 2015. Launched in May 2004, the company is a result of a merger of three major Thai film production companies of GMM Pictures (held 51%), Tai Entertainment (held 30%) and Hub Ho Hin Co. Ltd (held 19%) after the box-office success of their co-production of Fan Chan/My Girl in 2003. Despite the joint-venture nature, GMM Tai Hub acts as the de-facto film studio of Thailand's largest entertainment conglomerate, GMM Grammy PCL.

In 2000, Tai Entertainment along with Hub Ho Hin Bangkok co-produced its first Thai hit of the 2000s, The Iron Ladies', released in 2001. In 2003, Tai Entertainment and Hub Ho Hin had teamed up with GMM Pictures to produce Fan Chan/My Girl.

Due to internal conflicts in 2015, GMM Grammy and Hub Ho Hin rejoined to establish its new incarnation studio GDH 559 in 2016. Since then GDH now owns the catalog films produced and distributed by GTH along with its predecessor companies, GMM Pictures, Tai Entertainment and Hub Ho Hin Co. Ltd.

1st logo (April 2004-2006)
Logo: On a black background the blocks containing the letters 'G' in which the bottom parts are hidden and also forms the first letter of GMM Grammy's logo with 'GMM' below, 'ไ' (Thai equivalent of 'T') with ไท which translates to 'Tai' in Thai (also its bottom parts hidden), and 'H' with 'HUB', appear one by one.

Technique: The logo fading in.

Audio: None or opening theme of the movie.

Availability: Seen on older GMM Tai Hub films like Shutter. Note that in some earlier GMM Tai Hub/GTH films, it is preceded by the GMM Pictures logo.

2nd logo (2006-January 19, 2012)
z2WTlTQx8o8|width2=220|height2=165 uD80iQMfF14|width2=220|height2=200

Logo: On a white (or black) background, three dice with the letters 'G', a more readable 'ไ' which either looks like a 'T' or the number 7, and 'H' falls to a surface. After the 'H' is in its position, it swipes to its flat 2-D. logo. The letters 'G', 'ไ' and 'H' however, continues to be partly hidden similar with the first logo.

Variants:
 * The white or black backgrounds are used interchangeably (depending on the film genre).
 * There is another variant based on Suckseed, where the letters had morphed into band members (rendered in 2-D animation) jamming for a few seconds, the logo then animating as usual. It remains unknown if it had a sound variant and/or it is used in promotional materials of the film.

Technique: The falling dice and the swiping effect.

Audio: Either the remastered falling sound or depending on the film, the film's soundtrack.

Availability: Only seen in GTH films at that time such as Metrosexual, Hormones, Bangkok Traffic (Love) Story, Suckseed and Ladda Land.

3rd logo (July 26, 2012-December 28, 2015)

Logo: Same as before, but the logo seamlessly flips to a rounded rectangle, which makes it smoothly transition to a 2-D version of the logo. It is in a rounded rectangle form with the letters 'G', 'ไ', and 'H' now fully visible inside it.

Variants:
 * In the 2015 film Heart Attack, the film opening shows two versions of the logo. The first one is a still logo and it is in a smaller size. After the production and sponsor logos in-between, the second logo appears as usual. This sequencing became a common practice in GDH 559's titles after its establishment a year later in 2016.
 * A sea green variant of the logo exists, but it is only used on promotional material.
 * In 36, the logo's color is inverted to white in black background and it is used as an in-credit logo.

Technique: Same as before.

Audio: A whimsical, low-pitched yet smooth musical scoring is heard.

Availability: It is seen in GTH films beginning 2012 with Seven Something and notably appears on hit Thai blockbuster films such as Pee Mak, and I Fine..Thank You..Love You, its last appearance being on May Who? Despite being credited as one of the production companies involved, the full logo does not appear in 36 and it is instead credited as a one of the supporting companies. Digital and Disney+ Hotstar prints retain this logo (along with the older GTH logos) despite GDH's ownership of their film catalog. The TV variant is only seen animated on OPAS2, as other TV series (notably in Hormones: The Series) use the still version.
