In 1991, the network became the first black-controlled TV company to be listed on the New York Stock Exchange. Starting the late 1990s, the network expanded with the launch of digital cable networks: what is now the general interest channel BET Her originally launched as BET on Jazz (later known as BET Jazz and BET J), created originally to showcase jazz music-related programming, especially that of black jazz musicians; in 1998, it entered into a joint venture with Starz (then-owned by John Malone's Liberty Media) to launch a multiplex service of the premium channel featuring African American-oriented movies called BET Movies: Starz! 3 (later renamed Black Starz after BET dropped out of the venture following its purchase by Viacom, then-owner of Starz rival Showtime, and now known as Starz InBlack). In 2001, the network lost its status as a black-owned business when it was bought by media conglomerate Viacom for $3 billion. In 2005, Johnson retired from the network, turning over his titles of president and chief executive officer to former BET vice president Debra L. Lee.
