Law & Order: Special Victims Unit (often shortened to Law & Order: SVU or SVU) is an American police procedural crime drama television series created by Dick Wolf for NBC. The first spin-off of Law & Order, it starred Christopher Meloni as Detective Elliot Stabler until Meloni left the series in 2011 after 12 seasons, and Mariska Hargitay as Detective (ultimately promoted to captain) Olivia Benson, now the commanding officer of the Special Victims Unit after originally having been Stabler's partner in a fictionalized version of the New York City Police Department.
