tedlistens writes: On August 11, 1994, 21-year-old Dan Kohn, founder of a pioneering, online commerce site, made his first web sale. His customer, a friend of his in Philadelphia, spent $12.48, plus shipping costs on Sting's CD "Ten Summoner's Tales," in a transaction protected by PGP encryption. "Even if the N.S.A. was listening in, they couldn't get his credit card number," Kohn told a New York Times reporter in an article about NetMarket the following day. According to a new short video about the history of online shopping, there were a few precedents, including a weed deal between grad students on the ARPANET and a 74-year-old British grandmother who in 1984 used a Videotex—essentially a TV connected to telephone lines—to order margarine, eggs, and cornflakes.
