 As a possible outgrowth of this sales joint venture, MCA and Paramount began plans for a new network, Premier Program Service.In 1999, Viacom acquired several other TV production firms such as Spelling Entertainment Group (which owned Spelling Television, Worldvision Enterprises, Republic Pictures Television, and Big Ticket Entertainment) and Rysher Entertainment (or at least its library).As a result, the size of Paramount's TV library more than tripled, giving PDT a slew of new series to distribute.
