Overview
Siam Inter Multimedia is a Thai mass-media company associated with comic and novel publishing, particularly through the Siam Inter Comics and SMM Publishing imprints. Its publishing catalogue included translated and locally distributed comics and novels for Thai readers, while its broader media activities included the SMM Sport sports-news network. The company began in 1990 under the name Siam Comics Co., Ltd., establishing its initial identity around comics publishing. It later expanded its publishing and media scope and became a public company in 2003 under the name Siam Inter Multimedia Public Company Limited. The company was subsequently listed on the Stock Exchange of Thailand in 2005. One of its best-known publications was C-Kids, a Thai-language shonen manga magazine launched in 1994. C-Kids became one of the leading publications of its type in Thailand and was positioned alongside Nation Edutainment's Boom as a major manga magazine in the Thai market. The magazine continued publication until 2016, making it a significant part of the company's publishing history and of Thailand's modern manga readership culture. Siam Inter Multimedia also operated beyond print publishing through SMM Sport, a sports-news network. This reflected the company's development as a broader media business rather than a publisher limited to books and comics. The available reference material does not establish the full extent, duration, or present status of the sports operation. A major corporate restructuring occurred in 2019. Siam Inter Multimedia divested all of its operations to a newly created subsidiary, SMM Plus Co., Ltd., which became the operating entity associated with the business. In the same period, the parent company was acquired as part of a backdoor listing and became Stark Corporation. These changes separated the historical Siam Inter Multimedia corporate structure from the operating activities transferred to SMM Plus. The current status of the Siam Inter Multimedia name as a standalone operating brand is not fully established by the available reference material.
History
Siam Inter Multimedia traces its origins to 1990, when it was established as Siam Comics Co., Ltd. The original business was built around comic publishing in Thailand, a field that later developed into a wider catalogue of manga, comics, and novels. The company's publishing activities were conducted through imprints including Siam Inter Comics and SMM Publishing. The company's most prominent publishing property was C-Kids. Introduced in 1994, the Thai-language shonen manga magazine became one of the leading titles in its category. It operated in a competitive market that also included Boom, published by Nation Edutainment. C-Kids remained in publication until 2016, giving it a long run within the Thai manga-magazine sector and making it an important part of Siam Inter Multimedia's public identity. As the business developed, its activities expanded beyond books and comics. Siam Inter Multimedia operated SMM Sport, a sports-news network, indicating an effort to participate in the broader Thai mass-media market. The available material identifies the network but does not provide enough detail to document its launch date, specific channels, audience, or later operating history. In 2003, the company became Siam Inter Multimedia Public Company Limited. It was subsequently listed on the Stock Exchange of Thailand in 2005. The public-company phase represented a change in corporate scale and financing structure, although the available reference does not provide financial performance, share-price information, or details of the company's board and executives. The next major transition came in 2019. Siam Inter Multimedia transferred all of its operations to a newly created subsidiary, SMM Plus Co., Ltd. Around the same time, the parent company was acquired as part of a backdoor-listing transaction and became Stark Corporation. This restructuring altered the relationship between the historical listed company and the operating publishing and media activities. The reference material does not establish whether Siam Inter Multimedia continues as a consumer-facing brand, whether all publishing imprints remained active, or how the business subsequently developed under SMM Plus.
