George Levine pioneered the electrification of the financial markets with a terminal that brought real-time stock bids to Wall Street in the 1960s. The terminals featured prominently in Oliver Stone's "Wall Street." Quotron was sold to Citicorp in 1986 before being taken over by Thomson Reuters in 1994.
Levine joined Scantlin Electronics, which electronically stored and retrieved stock market information, in 1963, a time when most people had to rely on newspapers to check stock prices on the New York Stock Exchange. The company changed its name in the 1970s to Quotron, the name of a workplace terminal that displayed stock bids, offers and last sale prices on electronic screens instead of ticker tape. Quotron terminals were ubiquitous in the financial services industry, making cameos in Oliver Stone's 1987 film "Wall Street," and later in Martin Scorsese's 2013 throwback "Wolf of Wall Street."
