On September 20, 1999, NBC premiered a new show that was a spinoff from the wildly successful Law & Order. The first spinoff in the Law & Order franchise, Law & Order: Special Victims Unit, was centered around Detective Elliot Stabler (Christopher Meloni), Detective Olivia Benson (Mariska Hargitay), and their colleagues in the NYPD's 16th precinct. While Wolf Entertainment and NBC anticipated good things from the show, no one could have predicted how SVU would change not just television but also the rhetoric around sexual assault and domestic violence. Countless viewers also credit the show with helping them decide to report their sexual assault and even with helping them heal from their trauma.
