Industry History
The history of the Lobbyists industry dates back to ancient Rome, where advocates were hired to plead cases in the Roman Senate. In the United States, the first lobbyists were hired in the late 1700s by the state of New York to represent its interests in the federal government. The industry grew rapidly in the 20th century, with the establishment of lobbying firms and trade associations. Notable advancements include the Lobbying Disclosure Act of 1995, which required lobbyists to register with the government and disclose their clients and fees. In recent years, the industry has faced increased scrutiny and regulation, with the passage of the Honest Leadership and Open Government Act of 2007 and the Lobbying Disclosure Enhancement Act of 2007, which increased disclosure requirements and restricted gifts and travel for lawmakers. Lobbyists have also faced criticism for their role in shaping public policy and the perception that they represent special interests rather than the public interest.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification. It is not an official U.S. Census Bureau NAICS code. Its parent industry is an official NAICS classification defined by the U.S. Census Bureau. Classifications are reviewed regularly by SICCODE.com's Classification Review Team.
SICCODE.com classifies companies under both Extended NAICS and Extended SIC. A company may appear in both classification systems, so company counts should not be added together without deduplication.
