The world wide web is both a fairly new medium as well as an ever changing and ever growing one, and because of this many legal issues remain unclear and subject to change regarding Internet law. Business owners often consult attorneys with specific knowledge and experience with information technology laws and other issues relating to the Internet. Attorneys who specialize in Internet law often help business owners with matters relating to e-commerce, software issues, and trademark or copyright infringement issues. Companies may also consult attorneys when creating Internet usage policies for their employees. According to current legal decisions regarding Internet law, business owners generally have the right to monitor and/or restrict their employees Internet usage in order to protect their business from online risks as well as lost time and productivity due to excessive personal Internet usage by employees. While the Internet is a global entity, specific rules relating to Internet law often differ dramatically depending on physical location. Because of this, business owners operating in countries outside the United States may often be subject to different rules and regulations.
