The use of electronic surveillance by the United Kingdom grew from the development of signal intelligence and pioneering code breaking during World War II. In the post-war period, the Government Communications Headquarters (GCHQ) was formed and participated in programmes such as the Five Eyes collaboration of English-speaking nations. This focused on intercepting electronic communications, with substantial increases in surveillance capabilities over time. A series of media reports in 2013 revealed bulk collection and surveillance capabilities, including collection and sharing collaborations between GCHQ and the United States' National Security Agency. These were commonly described by the media and civil liberties groups as mass surveillance. Similar capabilities exist in other countries, including western European countries.

In June 2013, the first of Snowden's documents were published, with further selected documents released to various news outlets through the year.
