One of the earliest known uses of the Internet as a medium for activism was that around Lotus MarketPlace. On April 10, 1990, Lotus announced a direct-mail marketing database product that was to contain name, address, and spending habit information on 120 million individual U.S. citizens. While much of the same data was already available, privacy advocates worried about the availability of this data within one database. Furthermore, the data would be on CD-ROM, and so would remain fixed until a new CD-ROM was issued.
