Information on end credits

I found this information on wikapedia about the different ways of how end credits may appear in a film:

Closing credits or end credits are added at the end of a motion picture, television program, or video game to list the cast and crew involved in the production. They usually appear as a list of names in small type, which either flip very quickly from page to page, or move smoothly across the background or a black screen. Credits may crawl either right-to-left (common in U.K. television programs) or bottom-to-top (common in films and U.S. television). The term credit roll comes from the early production days when the names were literally printed on a roll of paper and wound past the camera lens. Sometimes, post-credits scenes or bloopers are added to the end of films along with the closing credits.
