This is not the same as a government-owned corporation.

A public company, publicly traded company, publicly held company or public limited company (in the United Kingdom) is a limited liability company that offers its securities (stock/shares, bonds/loans, etc.) for sale to the general public, typically through a stock exchange, or through market makers operating in over the counter markets. Public companies, including public limited companies, can be either unlisted or listed on a stock exchange depending on their size and local legislation.

Sometimes government-owned companies are confusingly called public companies. This kind of company is better described as a publicly owned company or government-owned corporation.

Usually, the securities of a publicly traded company are owned by many investors while the shares of a privately held company are owned by relatively few shareholders. A company with many shareholders is not necessarily a publicly traded company. In the United States, in some instances, companies with over 500 shareholders may be required to report under the Securities Exchange Act of 1934; companies that report under the 1934 Act are generally deemed public companies. The first company to issue shares is generally held to be the Dutch East India Company in 1601^{[citation needed]}, but quasi-corporate entities, often trading or shipping concerns, are known to have existed as far back as Roman times.
