First point-of-sale records system

According to Official Guinness Records,

It’s been said, and with some justification, that the most widely published fiction is most publishers’ sales figures. Fiction was transformed into fact, however, with the setting-up of the world’s first point-of-sale records system for books. Launched in January 2001, Nielsen BookScan records point-of-sale data from 33,500 bookshops around the world to produce the most accurate record of worldwide book sales so far produced.
