In recent years, economic or industrial espionage has taken on an expanded definition. For instance, attempts to sabotage a corporation may be considered industrial espionage; in this sense, the term takes on the wider connotations of its parent word. That espionage and sabotage (corporate or otherwise) have become more clearly associated with each other is also demonstrated by a number of profiling studies, some government, some corporate. The United States government currently has a polygraph examination entitled the "Test of Espionage and Sabotage" (TES), contributing to the notion of the interrelationship between espionage and sabotage countermeasures. In practice, particularly by "trusted insiders", they are generally considered functionally identical for the purpose of informing countermeasures.
