censors specifically hired by provincial authorities to screen movies confiscated from unlicensed dealers for pornographic content. The government has launched campaigns to crack down pornography to "protect minors and maintain public morality", but pornography consumption within the country has grown steadily since 2000. Censorship bodies generally treat LGBT content as immoral, and regularly censor non-pornographic depictions of such content in mass media. Positive depictions of same-sex relationships in movies and television have been taken off the air by censors, and according to Human Rights Watch, negative depictions of LGBTQ people are "common and pervasive" as of 2015. Global controversy erupted in 2018 when Mango TV edited out Ireland's Eurovision song because it depicted two men holding hands and dancing together. An LGBT flag waved during an earlier performance by Switzerland that year was also blurred out. The European Broadcasting Union subsequently terminated its relationship with Mango TV's parent company, Hunan Broadcasting System, preventing any further airing of the Eurovision Song Contest in China. Censors had also cut Albania's 2018 performance because of the lead singer's tattoos. In 2021 the National Radio and TV Administration added a ban on "sissy men and other abnormal esthetics" to its rules using the offensive term niang pao. Cultural China has historically sought to use censorship to protect the country's culture. During the Cultural Revolution of the 1970s, foreign literature and art forms, religious works and symbols, and even artifacts of ancient Chinese culture were deemed "reactionary" and became targets for destruction by Red Guards. Although much greater cultural freedom exists in China today, continuing crackdowns on banning foreign cartoons from Chinese prime time TV, and limits on screening for foreign films could be seen as a continuation of cultural-minded censorship. The foreign TV shows and films on internet also become the target of censorship. In July 2017, Bilibili, one of the most popular video sites in China, removed most of American & British TV shows, and all foreign categories like "American drama" to comply with regulations. In order to limit outside influence on Chinese society, authorities began to restrict the publishing of children's books written by foreign authors in China from early 2017, reducing the number of these kind of books from thousands to hundreds a year.
