Interstate commerce clause interpreted and used?

The Interstate Commerce Clause, found in Article I, Section 8 of the U.S. Constitution, grants Congress the power to regulate commerce among the states. It has been interpreted broadly to include not only the buying and selling of goods but also the movement of people and services, as well as economic activities that may affect interstate commerce. Landmark Supreme Court cases, such as Gibbons v. Ogden and Wickard v. Filburn, have reinforced this expansive interpretation, allowing federal regulation over a wide range of activities. As a result, the clause has played a crucial role in shaping federal-state relations and promoting national economic unity.
