Definition of Cb simulator

At that time, most people were familiar with Citizens' band radio, often abbreviated as CB radio, but multi-user chat did not yet exist and instant messaging was largely unknown. CompuServe CB used the CB radio paradigm to help users understand the new concept. Like CB radio it had 40 "channels" and commands like "tune", "squelch", and "monitor." CompuServe CB quickly became the largest single product on CompuServe despite virtually no marketing. When 40 channels wasn't enough, additional "bands" were added, such as the "Adult" band.
