Traditionally, retail home video releases of Saturday Night Live material have consisted of "Best Of" compilations, comprising select performances of past cast members, and notable guest hosts. Beginning in 1999, DVD releases were distributed by Lions Gate Home Entertainment under license from NBC, predating the network's merger with Universal, following Lions Gate's acquisition of NBC's previous distributor Trimark. Following the establishment of NBCUniversal in 2004, Universal Studios, owners of NBC, Saturday Night Live's broadcast home, ceased the existing arrangement of outside distribution of SNL material. While Lionsgate is no longer able to acquire new SNL-related content, they have retained reissuing rights to their existing SNL content library.
