b'1977By 1977, things were beginning to collapse for NSS. . Multi-screen theaters were drastically cutting into the accessory market, and other companies were taking over the trailer market. National Screen Service made a bold move in 1977 to try to reorganize the handling of their product lines and streamline the processing. To do this, they had to make the numbering systems uniform again and a slash (/) in the middle of the number would not work. NSS changed the accessory number BACK to the original trailer number system featuring two numbers for the year and then 4 numbers for the individual number. This was instituted during 1977, but it was not done at a specific point and by all offices at the same time, so it creates an inconsistency for the year. 1978-1989By the 1980s, the writing was on the wall. Each year the number of titles declined as fewer varieties of accessories were needed. NSS began shutting down offices and selling off the posters. In 1984, it was no longer profitable so National Screen Service relinquished exclusivity on the studio accessories and turned the operation over to the individual studios. In 1987, with business declining, they made a small adjustment to their number system. The regular numbering for the titles remained the same, but they started using the upper numbers (3000 series) for special printing jobs. These were for individual pieces and NOT for titles. By the late 1980s, NSS had cut down to three offices nationally (just like they had in the 1920s). They did some printing and distributing but each year business continued to decline. In 1990, NSS changed their numbering system from a single number for a title to a single number for a single item. So if three different items were produced for a single title, it would have three different numbers. This continued until 2000 when Technicolor bought them out and closed down the remaining three offices. THE NSS CONTRIBUTIONIt goes without saying that the National Screen Service had a direct and positive impact on the film industry, particularly in its growth years from the 1920s to the 1960s.But their contribution does not stop there.The work logs that NSS created, albeit designed for their business purposes, left an undeniable historical blueprint of the film industry in the United States.These records provide an invaluable resource for film and memorabilia collectors, dealers, historians and archivists.'
