Freedom of information is an extension of freedom of speech, a fundamental human right recognized in international law, which is today understood more generally as freedom of expression in any medium, be it orally, in writing, print, through the Internet or through art forms. This means that the protection of freedom of speech as a right includes not only the content, but also the means of expression. Freedom of information also refers to the right to privacy in the content of the Internet and information technology. As with the right to freedom of expression, the right to privacy is a recognised human right and freedom of information acts as an extension to this right. Lastly, freedom of information can include opposition to patents, opposition to copyrights or opposition to intellectual property in general. The international and United States Pirate Party have established political platforms based largely on freedom of information issues.
In June 2006 nearly 70 countries had freedom of information legislations applying to information held by government bodies and in certain circumstances to private bodies. In 19 of these countries the freedom of information legislation also applied to private bodies. Access to information was increasingly recognised as a prerequisite for transparency and accountability of governments, as facilitating consumers' ability to make informed choices, and as safeguarding citizens against mismanagement and corruption. This has led an increasing number of countries to enact freedom of information legislation in the past 10 years. In recent years, private bodies have started to perform functions which were previously carried out by public bodies. Privatisation and de-regulation saw banks, telecommunications companies, hospitals and universities being run by private entities, leading to demands for the extension of freedom of information legislation to cover private bodies.
