An ISP is an Internet service provider. Internet service providers offer access to the Internet to customers using varying forms of technology such as cable modems, DSL, dial-up connections, and wireless Internet connections. Laws and regulations governing ISPs vary greatly by state and country; ISP laws are also constantly being changed and modified to keep up with new legal issues that arise in regard to online activity. Lawmakers at the federal, state, and local levels have been essential in creating the rules and regulations regarding ISP laws, and have addressed a wide range of Internet issues such as spam, privacy, safety, and freedom to choose ISP carriers. Regulatory groups also have a large part in creating ISP laws. The Federal Communications Commission (FCC) and the Federal Trade Commission, as well as public utility commissioners often have a hand in making decisions regarding ISP laws. Judges, attorney generals, police agencies, and even the FBI and the Justice Department also handle ISP laws.
