Early court cases focused on the liability of Internet service providers (ISPs) for hosting, transmitting or publishing user-supplied content that could be actioned under civil or criminal law, such as libel, defamation, or pornography. As different content was considered in different legal systems, and in the absence of common definitions for "ISPs," "bulletin boards" or "online publishers," early law on online intermediaries' liability varied widely from country to country. The first laws on online intermediaries' liability were passed from the mid-1990s onwards.[citation needed]
