Traditional Chinese opera (Xiqu) became a popular source of public entertainment in the late 19th century. In the early 20th century, monologue and burlesque in Shanghainese appeared, absorbing elements from traditional dramas. The Great World opened in 1912 and was a significant stage at the time. In the 1920s, Pingtan expanded from Suzhou to Shanghai. Pingtan art developed rapidly to 103 programs every day by the 1930s because of the abundant commercial radio stations in the city. Around the same time, a Shanghai-style Beijing Opera was formed. Led by Zhou Xinfang and , it attracted many Xiqu masters, like Mei Lanfang, to the city. A small troupe from Shengxian (now Shengzhou) also began to promote Yue opera on the Shanghainese stage. A unique style of opera, Shanghai opera, was formed when local folksongs were fused with modern operas. As of 2012, prominent troupes in Shanghai include Shanghai Jingju Theatre Company, , Shanghai Yue Opera House, and Shanghai Huju Opera House.
