Showtime Championship Boxing, which was very similar to HBO World Championship Boxing, featured Mauro Ranallo on play-by-play, Al Bernstein as the color analyst, Jimmy Lennon (Sr. and Jr.) as ring announcers, and Jim Gray as reporter.

A sister program, ShoBox: The New Generation, has occasionally aired on Friday nights, featuring fights between boxing prospects.

Amir Khan, Austin Trout, and Daniel Jacobs have served as guest analysts.

The third role was previously filled by Antonio Tarver, Ferdie Pacheco, Bobby Czyz, and Paulie Malignaggi among others.

The New Generation features Barry Tompkins on blow-by-blow, and Raul Marquez and Brian Campbell as the expert analysts.
