GMMTV Company Limited is a Bangkok production house and artist management company that began operating on 3 August 1995 under the name Grammy Television Company Limited. It worked inside GMM Grammy for its first twenty five years and has been a subsidiary of The One Enterprise since December 2020. Its offices sit at GMM Grammy Place on Sukhumvit Road.

The company describes its own business as three things at once: managing artists, producing television and making films. In practice that means one organisation casts a series from a roster it also trains and represents, produces the episodes, releases the soundtrack and books the same performers for the variety programming that surrounds the show. That roster runs to more than two hundred actors, presenters and singers, and in January 2023 the company added a music label, Riser Music, to release their recordings.

Much of what it puts on screen begins as a Thai novel or a webtoon, so a GMMTV record on this site very often has a book behind it. Finished episodes reach viewers through the GMM 25 and One 31 channels, the company's own YouTube channel and licensed streaming services, and each year's slate is introduced at a single annual line up presentation.

Studio Wabi Sabi Company Limited is a Thai production house registered in Bangkok under the business activity of television programme production, and listed in Thailand's national content industry directory as a film production company with offices in the RCA area of Huai Khwang.

It was founded by the director and producer Siwaj Sawatmaneekul, known professionally as New, who still heads it. He has said the studio was set up around the making of its first official project, the series Dai Daeng, released in English as The Red Thread, and that it started with three employees. As the company grew he moved from directing everything himself to producing while other directors take the floor, which is why the director credit on the records below is not always the same name.

He has also described the studio as working something like a school for performers, bringing people in early and developing them across several productions rather than casting each series from nothing. On this site that shows up as the same faces returning through the studio's records in different parts, sometimes as a lead, sometimes further down the call sheet. The company works in series rather than feature film, and each record below carries its own platform and episode detail.

Mandeework Co., Ltd., which signs its work Mandee, is a Thai production company registered in the Lat Phrao district of Bangkok and listed in Thailand's national content industry directory as a film production company. It works across series and film, with a slate that includes boys' love titles made for domestic broadcast and for streaming.

Its public output runs through a YouTube channel called Mandee Channel, published under the handle MandeeWork, which carries episodes, trailers and music video content rather than acting as a shop window for a separate site. Published reference entries on Domundi TV name Mandee Channel as that company's parent, and the channel itself lists Domundi and DMD among its own keywords, so records credited to one of these names frequently share personnel with the other.

For a viewer using this site the practical consequence is that a Mandee credit and a Domundi credit are worth reading together. Cast members, directors and crew move between the two, and a series that carries one name in its opening titles may carry the other in its distribution. Each record below lists its own credits, platform and episode count as recorded here.

The One Enterprise Public Company Limited trades on the Stock Exchange of Thailand under the ticker ONEE, where it has been listed since 5 November 2021. Its roots go back further than the current name. It grew out of two production companies founded by Takonkiet Viravan, Exact in 1991 and Scenario in 2004, which were brought together under the present structure in 2013.

It is a group rather than a single studio, and that is what makes its name appear on a production credit. It operates the Channel One 31 and GMM 25 television channels and the radio stations EFM, Green Wave and Chill Online, and its group companies include one31, GMMTV, Change2561, GMM Media, GMM Studios, Exact Scenario, ACTS Studio and ATIME. Several of those names appear elsewhere on this site in their own right.

The company describes itself as covering the whole chain from production through to distribution, across drama, sitcom, series, variety and news programming. A record credited here is usually one where the parent company itself is named on the production, rather than one of the group studios listed separately on this site.

Domundi TV Co., Ltd. was founded on 3 August 2016 by Kittipat Jampa, who works as a director and manager and is known as Aoftion. Published reference entries name Mandee Channel as its parent company. It is based in Bangkok and describes its business as three things together: artist management, television production and music production, with boys' love series as the centre of what it makes.

The company has no separate corporate website. Its YouTube channel serves that purpose, and is also where much of its output is published. The artists it manages, more than forty of them, are organised into numbered intakes labelled DMD GEN 1 through GEN 5, so a performer's generation is part of how the company itself describes them.

Two habits make its records recognisable. Since 2023 it has run DMD Friendship the Reality, a reality format in which pairings are formed on screen and lead roles in the company's own dramas are awarded as the prize, which means some casting decisions are public before the drama exists. And it works as a music company as well, announcing the six member group DEXX in June 2025 and debuting them the same month.

Change2561 Co., Ltd. took its name from the year it was founded. The company began on 20 April 2018, and 2561 is that year in the Thai Buddhist calendar. It is led by Saithip Montrikul Na Ayutthaya as chief executive, works from GMM Grammy Place on Sukhumvit 21 in Bangkok, and has Worarit Waijaeranai among its named key people.

It started life as a fifty fifty joint venture between GMM Grammy, through GMM Holding, and Adelfos. Both original shareholders later sold their stakes to The One Enterprise, which lists Change2561 today as one of its group companies alongside the One 31 channel and GMMTV.

The business is deliberately broad. Alongside drama series it covers television programming, entertainment industry coverage, live events and digital content, and it manages artists and stages music events of its own. Its chief executive has stated publicly that the company sets out to build content from true stories in order to inspire and encourage people, which is a clearer statement of editorial intent than most production houses put on record, and a useful thing to have in mind when reading the records collected here.

Avex Pictures Inc. is the video arm of Japan's Avex group, established on 1 April 2014 when the video package operations of two earlier group companies, Avex Entertainment and Avex Marketing, were brought together into a single business. Three existing labels, avex mode, avex pictures and DIVE II entertainment, moved across with them. The company is capitalised at one hundred million yen and works from Minato in Tokyo.

It describes its own business as the planning, production and sale of video content, and it also manages voice actors and artists, which is unusual for a production company and means the same organisation can cast, record and release an animated title. Its group includes the subsidiaries Anime Times and Flagshipline, the second of these set up in 2018 as a joint venture with the animation studio Graphinica.

On 1 August 2023 the company reorganised. Two wholly owned subsidiaries were created, Avex Animation Labels for animated content and Avex Film Labels for live action, with Avex Pictures itself moving to an overseeing role above them. Records here credited to Avex Pictures may therefore sit on either side of that change.

Two titles carry this name on the production side, and they do not carry it in the same way. On Your Sky: Hare Nochi Koi, the 2026 Japanese remake of a Thai series, the station is credited as a production partner alongside Mandee Work and The Works, which is a real share in making the programme. On Unexpectedly Naughty Fukami it is the broadcaster, and the production credit belongs elsewhere. Reading the two records together is the only way to see that difference.

The station itself is an independent free-to-air broadcaster serving Tokyo and the neighbouring prefectures, and it has a separate archive on this site in its role as a network, where its broadcast credits are gathered. Keeping the two pages apart is deliberate: one records what a company helped make, the other records where something was shown. With two entries there is no trend to describe, only a distinction worth holding on to.
