WCW Monday Nitro made it's debut in September 1995 and ran until March 2001-that's almost six years of top notch action. Along with the WWF's Monday Night Raw, Nitro was a brilliant programme.
Along the way we had the big guns such as Hulk Hogan, Sting and Ric Flair but the great thing about Nitro was the way it highlighted some of the undercard wrestlers such as Billy Kidman and Rey Mysterio Jr.
Nitro was a very unpredictable programme for a long while. In one edition Lex Luger made a surprise return to WCW after wrestling in the WWF 24 hours earlier. You never knew what would happen on Nitro-anybody could show up, friendships could be broken up and throughout the series there were some wild brawls.
I strongly recommend tracking down old WCW Nitro tapes particularly from the 1996-1998 era.
