"Today, many OSCE participating States are reacting to the availability and dissemination of certain types of (illegal or unwanted) content through the Internet by trying to regulate or control its dissemination. There is particularly major concern about the availability of terrorist propaganda, racist content, sexually explicit content including child pornography, as well as content defined as hate speech on the Internet. This OSCE-wide Internet content regulation study involves a comprehensive overview of existing international legal provisions and standards relating to media freedom and freedom of expression on the Internet. The study will assess whether and how these are incorporated into national legislation and applied by the OSCE participating States." (Executive summary)
