n.
Any attempt by a group or individual to influence the decisions of government.
The term originated in 19th-century efforts to influence the votes of legislators, generally in the lobby outside a legislative chamber. The effort may be a direct appeal to a decision maker in either the executive or legislative branches, or it may be indirect (e.g., through attempts to influence public opinion). It may include oral or written efforts of persuasion, campaign contributions, public-relations campaigns, research supplied to legislative committees, and formal testimony before such committees. A lobbyist may be a member of a special-interest group, a professional willing to represent any group, or a private individual. In the U.S., the Federal Regulation of Lobbying Act (1946) requires that lobbyists and the groups they represent register and report contributions and expenditures.
