The pop music industry thrived by the 1980s, with several recording companies producing Chinese records by local as well as Taiwanese singers. Starting in the mid 1980s, a genre of Mandarin ballads called "xinyao" began to emerge with singers and/or songwriters such as Liang Wern Fook, Lee Shih Shiong, and Billy Koh. Local music labels such as Ocean Butterflies International and Hype Records were established. From the 1990s onwards, many Singaporean singers such as Kit Chan, Stefanie Sun, JJ Lin, Tanya Chua, Corrinne May, Fann Wong, and Mavis Hee had achieved wider success outside of Singapore.
