What are Internet blocking programs?
Internet blocking programs (also known as “filtering programs” or “censor-ware”) are computer programs designed to prevent access to certain Web sites. N2H2, Inc., the defendant in this case, develops, markets and licenses a blocking program that prevents computer users from accessing content that has been categorized by N2H2 as objectionable. Part of the program is a list of sites to block – its “block list” – that contains hundreds of thousands of Web sites representing millions of pages of Web content.
