The Drive for Diversity (D4D) program is a development system instituted by the American auto racing league NASCAR.
 The program's purpose is to attract minority and female individuals to the sport, primarily as drivers, but also including ownership, sponsorship, and crew member roles, and to attract a more diverse audience to the sport.
 Before an applicant is accepted into the program, their resumes are checked by NASCAR officials.
 The system is similar to a driver development program where applicants progress through minor-league and regional racing levels to prepare them for a possible shot at one of NASCAR's three national series.
 The program was started during the 2004 season by NASCAR marketing executives in order to attract minority fans and drivers to the historically white and male-dominated sport.
 The year before, Joe Gibbs Racing, along with former athletes Reggie White and Magic Johnson, had started a similar program.

A color commentator is a North American term for a sports commentator who assists the main commentator, often by filling in any time when play is not in progress.
 In other regions this role is variously referred to as an analyst or summariser.
 The color analyst and main commentator will often exchange comments freely throughout the broadcast, when the play-by-play announcer is not describing the action.
 The color commentator provides expert analysis and background information, such as statistics, strategy and injury reports on the teams and athletes, and occasionally anecdotes or light humor.
 Color commentators are often former athletes or coaches of the sport being broadcast.
In sports broadcasting, a sports analyst provides expert discussion of sports-related topics before, during, or after a sporting event.
 Sports analysts are frequently former athletes who participated in the sport being analyzed.
 A sports analyst is different from a sports commentator in that sports commentators provide a running commentary regarding a sporting event while the event is taking place, whereas sports analysts usually provide commentary about sporting events which have yet to take place or which have already concluded.
 The job of the color commentator is a hybrid of the two styles, providing expert analysis of a sporting event while the sporting event is taking place.
