Showtime Championship Boxing

Boxing After Dark is an HBO boxing program, premiering in April 1996, that usually shows fights between well-known contenders, but usually not "championship" or "title" fights.
 Unlike its sister program, "HBO World Championship Boxing", "BAD" features fighters who are usually moving up from ESPN's "Friday Night Fights" or another basic cable boxing program.
 This is where fighters are given their start to become famous depending on how well they fare on "BAD" they might have a title fight on "World Championship Boxing" or could fall back (Ex: Jason Litzau had many entertaining fights on ESPN before moving up to "BAD" to face Jose Hernandez.
 After Litzau lost by knockout he returned to "FNF")
