National Screen Service
The National Screen Service (NSS) was a company that controlled the distribution of theatrical advertising materials in the United States from approximately 1940 through the 1980s.As this greatly reduced the need for a separate organization to control poster distribution, movie studios took back those responsibilities, and NSS shrank.Also, NSS faced competition in the policy trailer and snipe business from other producers, namely Filmack and Pike Productions.NSS also created the main titles, end credits and optical effects, as well as distributing posters, stills and publicity material across the country.Movie advertising typically had the number in two places: stamped on the back by NSS, and printed in the lower-right corner.
