Sociedade de Turismo e Diversões de Macau

The Sociedade de Turismo e Diversões de Macau (STDM) is owned by Stanley Ho and his family. Historically it held a monopoly to Macao's gambling industry as the only licensee for casinos. In 2002, the Macao government began issuing more licenses and the monopoly was broken. Still, of the 17 casinos in operation in Macao, 14 are owned by Stanley Ho.
The company was founded in 1962 by Stanley Ho and his then partners Teddy Yip (Stanley Ho's brother-in-law through his sister, Susie Ho), Yip Hon and Henry Fok.
