In 2001 following WWF's acquisition of World Championship Wrestling, the Survivor Series match featured WWF against The Alliance. During 2003 and 2004 with the WWE brand extension, the event saw each Raw and SmackDown having their own match. In 2005 and 2008, there was only one match which saw Raw against SmackDown. However, 2016, 2017, and 2018 saw the Raw against SmackDown format return, with one men's, one men's tag team (except 2017), and one women's match. The 2019 event introduced three-way Survivor Series matches for both men and women with the addition of the NXT brand (along with its sister brand, NXT UK) in addition to both the Raw and SmackDown brands.
