Porn sites are often the leading platforms for the introduction and roll-out of new Internet technologies, thus driving the entire industry forward. For example, in the mid-1990s it was to pay for viewing pornographic content that Electronic Card Systems launched an online payment system using payment cards. Porn sites were also the first to use streaming broadcasts and video chats. Along with pirated music, pornography, according to research, was the main factor in the widespread spread of broadband internet in Europe.
