A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone. The use of bugs, called bugging, is a common technique in surveillance, espionage and police investigations.

Self-contained electronic covert listening devices came into common use with intelligence agencies in the 1950’s, when technology allowed for a suitable transmitter to be built into a relatively small package. By 1956, the U.S. Central Intelligence Agency was designing and building “Surveillance Transmitters” that employed transistors, which greatly reduced the size and power consumption. An all solid-state device had low enough power needs that it could be operated by small batteries, which revolutionized the business of covert listening.
