The show, which has been on the air for more than 22 seasons, has won over 33 Emmys, including an Outstanding Lead Actress in a Drama Series award for Hargitay. Law & Order: Special Victims Unit, which is by far the most successful spinoff from the franchise, premiered in September 1999 with Mariska Hargitay as Olivia Benson and Christopher Meloni as Elliot Stabler, two detectives in the Special Victims Unit of the New York Police Department.
