Shot at the world's largest ballroom dancing competition in Columbus, Ohio, the critically acclaimed show will this year air as a two-hour primetime broadcast event. In its fourth season America's Ballroom Challenge once again features 24 world-class couples competing across dance styles in pursuit of the title "America's Best."

All four major dance styles are featured — American Smooth, American Rhythm, International Standard, International Latin — with the focal point of the broadcast being the "show dances," where each couple has the floor to themselves. An international panel of judges will decide which couple walks away with the crown.

Actress, singer, and dancer Jean Louisa Kelly joins the series as co-host this season. Ms. Kelly's career has included leading roles on television, in feature films, and onstage. Seven-time U.S. National Latin Dance Champion Ron Montez returns to join Ms. Kelly as co-host of the series. America's Ballroom Challenge executive producer Aida Moreno first brought competitive ballroom dancing to PBS with Championship Ballroom Dancing in 1980.
