YY is a major Chinese video-based social network, a subsidiary of JOYY.

[1] It features a virtual currency which users earn through activities such as karaoke or creating tutorial videos and which is later converted to real cash.

Launched in 2005 as duowan.com (Nasdaq: YY), it originally targeted gamers, before broadening to include video streaming and chat features for uses such as concerts, fashion and sports.

[citation needed] The website was originally known as YY Voice (Chinese: 语音).

On 24 November 2014, YY's video streaming service began operating independently as Huya Live.
