Three new networks launched in the 1990s: within six days of each other in January 1995, The WB (which was originally formed as a venture between Time Warner, Tribune Broadcasting – which made the majority of its independent stations principal charter affiliates of the network – and former Fox executive Jamie Kellner, who served as The WB's original chief executive officer) and UPN (created as a programming partnership between Chris-Craft Industries/United Television and Paramount Television, which had been acquired the year prior by Viacom, which would gain full ownership of UPN five years after the network's launch) were launched primarily to compete against Fox, targeting the same younger demographic (teenagers and young adults 12 to 34) that network had built its success upon during the first half of the decade.
