Blogs range from personalized story-telling sites (for example, a teenager’s diary, and so on) to corporate communication tools (for example, a business customer service blog). As a general rule, many of the same legal principles that apply to websites apply to blogs—for example, reproduction of unauthorized materials requires permission unless excused by fair use principles. But there are also some rules and principles that are unique to blogging. This section provides a business and legal guide for bloggers including information on protecting and registering your content, protecting your blog’s name and avoiding other types of legal violations.
