The One Enterprise

The One Enterprise began in March 1990 when Takonkiet Viravan flew back to Thailand after graduating from university in the United States. He then started working at Grammy Entertainment Co., Ltd. (formerly name of GMM Grammy) and began working as a drama director for Master Plan Co., Ltd., a subsidiary of Grammy (now A-Time Media Co., Ltd.) of Yuthana Mukdasanit and Wanich Jarungkitanan, which was established on July 6, 1988, producing four television dramas that aired from 1989 to 1990. Boy was assigned to direct two new sitcoms for Master Plan, namely Nang Fah See Rung and Sam Num Sam Mum, which were both successful.

Exact

Later, Takonkiet wanted to produce his own dramas to be broadcast after the news, so he separated from Master Plan and established Exact Co., Ltd. and held the positions of producer, drama director, and managing director of the company himself. But it is also another subsidiary of Grammy for contract production of dramas, game shows, talk shows, variety shows, sitcoms, broadcast on various television channels. It was established on November 27, 1991. The company's first full-scale work was the drama "Rak Nai Roi Kaen" which aired in 1992 on Channel 5. Later, Exact was successful in producing many sitcoms until it became a leader in sitcom production in Thailand before Exact, including Master Plan, was acquired as a subsidiary of GMM Media Public Company Limited in November 2002.

Scenario

On April 9, 2004, Takonkiet expanded his business by establishing Scenario Co., Ltd., of which he currently holds 54.38%, GMM Media holds 25%, and Scenario artists, actors, and executives hold the remaining 20.62%. The company's objectives, similar to Exact's, are to produce shows for broadcast on various television channels, often in collaboration with Exact. However, Scenario has expanded its business beyond Exact by staging concerts and stage plays. It also later built and managed the Muang Thai Rachadalai Theatre on the 4th floor of Esplanade Ratchadaphisek, a joint venture with Muang Thai Life Assurance and Siam Commercial Bank, since 2007. This stage play and theater management business, Scenario, continues to operate today and since 2020 has also produced content for broadcasting on additional online channels, following the new vision of "More than a stage play." Jinnawat Siriwat is currently the Managing Director. In place of Takonkiet, who has been promoted to Chairman of the Board, Scenario is also the third largest shareholder in The One Enterprise today and was also an existing shareholder of The One Enterprise during its initial public offering.

Restructuring

On December 23, 2014, after GMM Grammy approved the sale of additional shares in GMM One TV Trading Co., Ltd. to Takonkiet and his group, the two shareholders entered into a joint agreement stipulating that Exact and Scenario would transfer all executives, production personnel, assets, and television production equipment, excluding the copyrights to Exact and Scenario's original content library, from GMM Media to GMM One TV Trading. This left Exact and Scenario with limited television business operations, primarily holding the copyrights to the original content library of television programs and dramas produced before the restructuring. Scenario would continue its stage plays and concert businesses, effective following the completion of the capital increase on March 27, 2015.

On August 24, 2017, Adelfos Co., Ltd., owned by the Sirivadhanabhakdi family, subscribed to additional shares of GMM Channel Trading Co., Ltd., the operator of GMM Grammy's GMM 25 channel business, which had also incorporated GMM Media into its subsidiary. The contract stipulated that GMM Grammy restructure its investment by directly acquiring and accepting the shares of Exact and Scenario, previously held by GMM Media, and transferring them to GMM Grammy as subsidiaries and associates.
