The show's place in the company was further devalued by the advent of "WCW Thunder" in 1998, airing on TBS and providing the secondary wrestling and storyline development that "WCW Saturday Night" had produced in the wake of "Nitro" burgeoning three-hour-long format. Once the cornerstone of the WCW wrestling empire, "WCW Saturday Night" ended its run in 2000 as the company struggled creatively to meet the demands of producing over six hours of new broadcast material on a weekly basis. The rights to "WCW Saturday Night" now belong to WWE as a result of that company's 2001 purchase of selected assets of WCW (including its video library).
