WHITE SLIPS NEWS BULLETINS (1885-1948)
In 1885, Charles Bergstresser at Dow-Jones had another idea to improve production. He got together with William R. Landfear, a Brooklyn inventor, to create some small printing presses based on Landfear's patent. They were hand-driven cylinder presses about half the size of a typewriter, and could print bulletins up to fifteen-lines (150 words).
These typeset bulletins were the first of their kind on Wall Street, and a big hit with brokers. Much preferred over the dirty old flimsies that stained clients' fingers. These little presses cut news slip production time in half, and they went from issuing 15 to 20 bulletins per day to 40 or more. By 1887 the bulletins were standardized at 5" x 9" and daily issues could surpass 100.
Two rival companies popped up, the Electric Bulletin Company (1886) and the New York News Bureau (1891), and they copied the idea, printing bulletins on yellow paper. Those became known as the "yellow slips" and Dow-Jones got the nickname "white slips"
Dow-Jones white slips clients received a brass clipboard (1890-1910) which attached to the wall, or a later 12" wood clipboard (1910-1948).
Widely-known as the "white slips," the Dow, Jones News bulletins are found in every important financial office in New York City. They supplement the Dow, Jones Electric Page Ticker, giving fuller comparative and detailed reports. The printed Bulletins, about nine by five inches, are turned out by specially constructed fast presses.
