For many years, pornography has been raising interest among people all over the world. In 2017, PornHub was visited 81 million times daily. USA, Germany, Great Britain, and Japan are the leaders in web searches related to porn.
Speaking about the popularity of pornography, the number of searches is not the only factor to be taken into account. It is essential that the more porn content is produced in a country, the more people are involved in the industry. Thus, in Japan, more than 5000 porn movies are released on a monthly basis.
