Lobbying is the act of attempting to influence the actions, policies, or decisions of officials, most often legislators or members of regulatory agencies. Lobbying, which usually involves direct, face-to-face contact, is done by many types of people, associations and organized groups, including individuals in the private sector, corporations, fellow legislators or government officials, or advocacy groups (interest groups).
"Direct lobbying refers to attempts to influence a legislative body through communication with a member or employee of a legislative body, or with a government official who participates in formulating legislation. Grass roots lobbying refers to attempts to influence legislation by attempting to affect the opinion of the public with respect to the legislation and encouraging the audience to take action with respect to the legislation. In either case, the communications must refer to and reflect a view on the legislation."
