The first changes made following the original rollout of the multiplex occurred in 2001, with the rebranding of BET Movies: Starz! as Black Starz! after BET withdrew from the partnership during its acquisition by Viacom (which owned rival pay service Showtime at the time) in 2001. A seventh Starz multiplex channel was launched in 2004: Starz! Kids was created as a movie service featuring films aimed at children between 2 and 11 years of age, maintaining a format similar to that of Starz! Family. Unlike the other Starz multiplex channels, Starz! Kids was launched on cable systems on a case-by-case basis instead of on a broader national scale.
